摘要
奥灰水的对煤矿得到安全生产由极大的影响,根据对老窑沟矿煤层带压情况的安全论证,提出了"综合防治,带压开采"的技术方案.根据断层煤柱留设后可布置工作面长度,2#煤 20203 工作面为最长 145 m;5#煤最长120 m,并对矿井排水能力进行了验证,进一步确定了带压开采的可行性.
Abstract
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.
