摘要
在深部煤层开采中,随着开采深度的增加,软岩增多,软化性质增强,巷道压力大,导致巷道底鼓甚为严重,影响了矿井的安全生产,增加了矿井的生产成本。找出巷道底鼓的成因和防治措施,对矿井的安全、经济效益有着重大的实际意义。
In deep coal mining, the soft rocks increased as mining depth went deeper, thus the soft effects strengthened, it caused that the roadway pressure increased, especially the roadway pucking phenomenon become seriously and impacted the mine safety, and the production cost went up. So it requires to find out the causes and prevention measures of raoadway pucking, and it has great actual meaning to the safety and economy effects of a mine.
