摘 要:通过对沙果园煤矿构造特征、地形地貌、矿井水文地质特征及矿井充水因素的分析,认为该矿煤层开采的直接充水含水层为山西组砂岩和野青灰岩、伏青灰岩含水层;对矿井安全生产威胁较大的充水因素为断层带充水和老空区充水,在以后的生产过程中要加强必要的探测,留设足够的防水、隔水煤柱,保证矿井的安全生产。This paper, according to the analysis on the structural characteristics, landform, hydrogeological features and water- filling factors of Shaguoyuan Coal Mine, finds out that the direct water-filling stratum are Shanxi Group sandstone and Yeqing limestone and Fuqing limestone aquifers. What threaten the safety production are the water-filling in the fault zone and old dead zone. Therefore, we should enhance the detection in the producing process and leave enough waterproof coal pillars to guarantee the safety production in mine.
