摘要
通过滕县煤田(南部)泉上煤矿井下实际揭露及钻孔资料,分析研究了十下灰岩、奥灰富水性特征及石炭二叠纪月门沟群对太原组16,17煤层开采的影响,认为在开采16煤层时,必须遵循“深部疏水降压,浅部采煤”的方针;在开采17煤层时,正常情况下不会受到奥灰水的威协;在井巷开拓过程中必须慎重对待十二灰,应先查明十二灰与奥灰的关系,防止奥灰底鼓水危害。
Through factual drilling information under the well in Quanshang coal mine of Tengxian coal mine, effects of limestones in the lower part of No. 10 stratum, water abundance characteristics and Yue- mengou formation in carboniferous-permian is analysed in this paper. It is regarded that in mining No. 16 coal stratum, the rule of "discharging and descending pressure in deep part, and mining coal in shallow part" should be followed. While in mining No. 17 coal stratum, water in Ordovician limestone will have no danger.
