在介绍矿区地质及水文地质条件的基础上,对矿井的充水因素进行了较为全面的分析,指出矿井的主要充水水源是山西组砂岩裂隙水、太原组灰岩岩溶裂隙水和奥陶系灰岩岩溶水;充水通道主要是断层破碎带和隐伏陷落构造,其次是采矿形成的冒落带和导水裂隙带。结合历年的突水资料,分析了三河尖煤矿历次发生水害事故的原因。针对煤矿充水特征,提出了在预防煤层顶板砂岩裂隙水和太原组灰岩岩溶水时,要以超前疏放为主,对奥陶系灰岩岩溶水,则应以“防”为主。
Based on the introduction of geological and hydrogeological conditions in the mining area, a comprehensive analysis is made of the water filling factors in the mine. It is pointed out that the main water-filling sources for the mine are sand-fissure water in Shanxi Formation, limestone karst fissure water in Taiyuan Formation and Ordovician Limestone karst water; water-filled channels are mainly fault fracture zone and concealed subsidence structure, followed by the caving zone and water-conducting fracture zone formed by mining. Combined with the data of water inrush over the years, the causes of previous water damage accidents in Sanhejian Coal Mine were analyzed. In view of the characteristics of waterflooding in coal mines, it is proposed that in the prevention of coal seam roof sandstone fissure water and limestone karst water in Taiyuan Formation, it is necessary to predominately dredge the limestone karst water in the Ordovician limestone. the Lord.
