### sec.61 Plans of coal mine workings The site senior executive for a coal mine must ensure survey plans of the mine’s workings include the following matters that may affect the safety and health of a person in the workings— the location of natural and artificial structures; surface drill holes. The site senior executive must also ensure the plans are sufficient to correlate separate sets of workings at the mine to allow the safe management of interfacing between the workings. Also, the site senior executive must ensure plans of the mine’s workings include— the following matters that may affect the safety and health of a person in the area of an adjacent or overlapping petroleum lease— the surveyed location of all abandoned mining equipment, including, for example, mobile plant and conveyors; the surveyed location and other details of all known incidents of spontaneous combustion; and the following information obtained in relation to mining through part of a coal seam that has been stimulated— the location of the stimulation; the observed extent and impact of the stimulation on the coal seam; the observed effect of the stimulation on the mineability of the coal seam. In this section— stimulation means a technique used to increase the permeability of a coal seam, including, for example, hydraulic fracturing, cavitations, fracture acidising, and the use of proppant treatments. s 61 amd 2020 SL No. 118 s 4 (sec.61-ssec.1) The site senior executive for a coal mine must ensure survey plans of the mine’s workings include the following matters that may affect the safety and health of a person in the workings— the location of natural and artificial structures; surface drill holes.
