由于地质钻孔数量有限,未能对断层含导水性进行有效分析,导致既不导水又不含水的断层留设了较大煤柱,严重影响工作面设计和生产系统布置,降低了煤炭采出率,不利于资源的充分开采利用。为此针对该矿YF20-3断层防水煤柱留设进行研究,以期能够采出呆滞煤炭储量,提高煤炭采出率,对于充分利用挖掘资源,稳定产量,延长矿井服务年限,实现可持续发展,具有重要的现实意义。

Due to limited number of geological drillings, water bearing and conductivity property of the faults can not be effectively analyzed. As a result, major pillars are reserved in water-free and nor conductivity faults, which seriously influence the design and production system layout of the face, reduce recovery ratio, and is not conducive to the resources exploitation and utilization. For this purpose, this paper presents study on waterproof pillar reservation and setting at YF20-3 fault of the coal mine, so as to mine the stagnant coal reserves and improve coal recovery rate, and offer practical significance for the full use of mining resources, stabilizing yields, extended coal mine service life, and the sustainable development.
