According to such a principle, it can be determined that the optimal vertical distance between the high suction roadway and the goaf floor is 39 m, and in this situation the gas concentration at the upper corner is 0.732%, which is an underspecified value of 1% prescribed in the coal mine safety rules. 4.2.
The aim of this paper is describing the optimal extraction path2 of exhaustible resource (coal) without and with CO 2 considerations. The description of the optimal extraction path will allow to compare and to see the changes in paths. Coal-related
The conventional method of mining for optimal coal extraction under such geo-mining conditions is splitting and stooking. The formation of stooks during the optimisation of recovery causes a considerable drop in strength of the natural support which is not desirable for long term stability of the underground mining and surface structures.
