Practice and Analysis of Coal Seam Pressure Mining
The safety production of coal mines is greatly affected by the use of Ordovician limestone water.Based on the safety demonstration of the pressure situation in the coal seams of Laoyaogou Mine,a technical scheme of"comprehensive prevention and control,pressure mining"is proposed.After setting up the fault coal pillar,the length of the working face can be arranged,with a maximum length of 145 meters for the 20203 working face of coal#2.The maximum length of 5#coal is 120 meters,and the drainage capacity of the mine has been verified,further confirming the feasibility of pressurized mining.
