5169/05 - MAITLAND MAIN COLLIERIES PTY LTD v HUNTER VALLEY COAL CORPORATION PTY LTD
JUDGMENT
1 HIS HONOUR: This is a dispute between two mining companies over land at Glennies Creek in the Upper Hunter Valley. The plaintiff, with others, operates the Glennies Creek Coal Mine. The defendant operates another coal mine in the vicinity at Mount Owen. Coal is moved from Mount Owen to the Great Northern Railway by rail and for this purpose the defendant constructed a spur railway line, which passes over the surface of part of the plaintiff's mine. The line was constructed in 1996.
2 It was necessary in 1995/96 for the defendant to secure the approval of a development application by the Singleton Shire Council in order to construct its railway line. The plaintiff objected to that development application.
3 The matter was resolved by the parties entering into a deed of release and indemnity bearing date 13 December 1995. I will simply refer to this document as "the deed".
4 The deed recites that the defendant wished to construct a rail line above coal lease 382, where the plaintiff intended to operate multi-seam longwall panels. The plaintiff referred to in the deed as MMC, the holder of that coal lease, would withdraw its objection to the Singleton Shire Council to the construction of the rail line provided that the defendant (HVCC) entered into the deed.
5 The operative part of the deed is as follows:
"1. MMC agrees to withdraw immediately its objection lodged with the Singleton Shire Council to the construction of the Rail Line by HVCC over the Land.
2. MMC will advise HVCC of its proposed second working applications and plans so as to give HVCC at least 6 months notice of extraction near the Rail Line and HVCC will not object to the proposed second working applications so disclosed to HVCC in accordance with this clause.
3. HVCC its contractors and agents shall abide by the conditions imposed by the Singleton Shire Council, the Department of Mineral Resources and the Mine Subsidence Board of New South Wales on the use of its Rail Line to allow MMC to maximise second workings.
4. HVCC hereby releases and indemnifies MMC from all claims costs demands losses or expenses in connection with damage to the Rail Line due to subsidence arising out of or in connection with MMC's underground mining activities carried out under Coal Lease No. 382 on the Land provided that the mining is carried out by MMC legally in accordance with approvals from the Department of Mineral Resources. Without limiting the generality of the above provisions of this clause, HVCC also indemnifies MMC from all costs that it may incur due to the need for extra remedial drainage work ("the incremental works") occasioned by the existence of the Rail Line beyond those works that would otherwise have been necessary. Should a dispute arise as to the necessity or extent of the incremental works it will be determined by an independent expert appointed by the President of the Australian Institute of Mining and Metallurgy whose decision shall be final and binding on the parties.
5. The parties acknowledge that HVCC intends to purchase certain land over which Coal Lease No 382 is held by MMC. In consideration for MMC entering into this Deed, HVCC shall not unreasonably withhold its consent or agreement to MMC entering upon any land owned by HVCC over which Coal Lease No. 382 exists for the purpose of exploration and development of roads or other services and infrastructure subject to the parties entering into a written agreement in relation to such entry on terms which are acceptable to both parties. Such agreement shall be binding on the successors and assigns of each party.
6. The provisions of this Deed shall bind the parties named in this Deed and their respective successors and assigns."
6 The negotiations which brought about the deed showed that the Department of Mineral Resources made it abundantly clear that it considered it essential that the coal in the plaintiff's mine was to be exploited to the full, and it also notified its objection to the line if it was going to impede the full exploitation of that coal.
7 Since December 1995 the procedure for approval of the second working of coal mines has changed and that brings about the present problem.
8 In 1995 the way in which one obtained consent of the relevant Minister to second working mining applications was to follow the guidelines which were issued by the Department, and which are AX02 in these proceedings.
9 Section 138(1) of the Coal Mines Regulation Act 1982, which has remained unchanged at all relevant periods, provides:
"1. No method of mining other than the bord and pillar system shall be used in an underground mine except with the approval of the Minister given on the recommendation of the Chief Inspector and subject to such conditions as the Minister may impose."
10 The application was made by letter, including a comprehensive report dealing with all technical and societal impact matters and a plan; the written report covered aspects of mine safety, resource recovery on mining subsidence and land use issues. The prime thrust of the Coal Mines Regulation Act was for the safety of coal mining and people working therein, but it is true that subsidence issues also had to be addressed in order to get the necessary Minister's approval.
11 However, by 2005 the way in which one could get permission for second working was changed. The procedure is set out in AX59 and AX60. The changed procedure involved a two-stage process. An approval under section 138 of the Coal Mines Regulation Act was not, as a matter of policy, to be granted until a subsidence management plan (SMP) had been prepared and approved by the Director-General of the Department of Primary Industries. The procedure to get an SMP was more procedurally difficult than it was under the 1995 procedure.
12 The application for an SMP was to be by letter addressed to the Director-General, with a written report, which not only was to deal with the proposed mining system and resource recovery, but was to deal with community consultation about the matter. The "plain English" version of the new policy makes it clear that not only must the title holder advertise its application, but it must also, before filing the application, fully report and discuss the views that it has obtained from affected landholders, local councils, the local aboriginal community and the general community, and discuss in the application how those views have been taken into account in the draft SMP. Moreover, the SMP was to include proposals for a subsidence community consultation process to continue after the plan had been approved by the Director-General. It is noted that it was to be approved by the Director-General, not by the Chief Inspector nor the Minister.
13 The new policy was also reinforced by adding conditions to the leases, including the relevant leases, requiring the lease holder to prepare an SMP prior to commencing any underground mining operations which will potentially lead to subsidence of the land surface. This could mean some first mining operations, as well as all second workings.
14 It is common ground that in the coal industry one first works an underground coal mine by bord and pillar, that is, one extracts the coal by cutting underground roadways or bords into the coal, while leaving blocks of coal or pillars to support the overlying rock strata from collapsing. This is known as first workings.
15 "Second workings" is a term used to refer to the total or partial extraction of the pillars. Longwall mining is one of the methods used to mine as a second working activity. As I understand, two parallel roadways are constructed on each side of the pillar or large blocks of coal and that coal is extracted using longwall mining equipment. This includes a shearer which moves backwards and forwards above an open conveyor to cut the coal face of the longwall block. Longwall removal almost always brings about subsidence.
16 The plaintiff has removed longwalls 1 and 6 from its mine and now proposes to remove longwalls 7 to 9. However, 7 to 9 are beneath the defendant's rail spur line and it is not at all happy with the proposal. In order to commence longwall mining the plaintiff needs (a) to submit an SMP, and (b) to obtain ministerial approval under s 138. It cannot, however, as I have said, obtain the latter until it has first had the SMP approved by the Director-General.
17 The plaintiff says that all that has really happened is that the 1995 procedure has been split into two parts; (a) the SMP and (b) the Minister's approval, so that the second working application referred it in cl 2 of the deed means both of those processes.
18 On the other hand, the defendant says that cl 2 only applies to the actual application to the Minister under s 138 and that it cannot be considered that an SMP application, which is a condition precedent to an application to the Minister, is an application under cl 2 of the deed.
19 The surface land above longwalls 7, 8 and 9 appears to be owned as to part by the defendant, part by some of its associated companies, Glendell Tenements Pty Ltd, Enex Foydell and Enex Ravenswood Pty Ltd, and also by an AC Noble and GJ Donnellan. Enex Foydell appears to own the surface over which the defendant had its spur line.
20 On the plaintiff's side of the record, the plaintiff is only a co-venturer in the Glennies Creek Colliery. This has been the situation at all times. However, in June 2005 the joint venture was reconstituted by the plaintiff transferring two-thirds of its interest to some Japanese and Korean interests. However, there was no novation under the deed.
21 The question before me is principally one of construction and was fully argued yesterday, Mr T F Robertson SC and Mr T G R Parker SC appearing for the plaintiff and Mr B R McClintock SC and Mr R Beasley appearing for the defendant.
