摘要
堡子煤矿2#煤层首采区,煤层底板标高750 m^990 m,奥灰水位标高931 m^936 m,面临带压开采问题。通过分析含水层、隔水层的特性,并根据《煤矿防治水规定》要求计算带压开采安全系数,对其带压开采可行性进行分析评价,提出安全技术措施,实现矿井安全生产。
Abstract： Standard height of coal seam floor is 750 m-990 m and ordovician limestone water level elevation is 931 m-936 m in first mining area in 2^# coal seam in Baozi Coal Mine, and there are some problems in mining above confined aquifer. Through analyzing characteristic of aquifer and water-resisting layer, analysis and evaluation of the feasibility for mining above confined aquifer were carried out, and safety factor for mining above confined aquifer according to the requirement of Provisions on Prevention and Control of Water in Coal Mines, safety technical measures were put forward in this paper, which realized the mine safety production.
