sec.317Risk assessment

### sec.317 Risk assessment The underground mine manager for an underground mine must ensure a risk assessment is carried out under this section to decide a safe method of extraction for second workings at the mine before the second workings start. The risk assessment must have regard to at least the following matters— any surface features, artificial structures and water reserves that may create a hazard if disturbed by the workings; any other workings located in close proximity above, below or adjacent to the proposed second workings, whether in the same or an adjacent mine; the known geology affecting the intended workings; the anticipated gas make; the pillar stability; the proposed method and sequence of coal extraction; the proposed methods for the following— strata control and support; ventilation; controlling spontaneous combustion; support methods necessary to control the edges of each goaf area in active workings; the suitability of the plant, and its controls, used for the workings.
