| 摘 要： | 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。

| Abstract: | Based on the introduction to the mine area geological and hydrogeological conditions,carried out rather all-around analysis of mine water filling factors,pointed out that the main water filling sources have Shanxi Formation sandstone fissure water,Taiyuan Formation limestone karstic fissure water and Ordovician limestone karstic water.The main water filling channels have shattered fault zones and hidden subsided structures,while the mining formed caving zones and water conducted zones are secondary.To use water bursting data in the past years analyzed causation of all previous water disasters happened in the Sanhejian coalmine.In allusion to coalmine water filling characteristics,considered that,in guard against coal roof sandstone fissure water and Taiyuan Formation limestone karstic water should take the advanced mine dewatering as the main measure,while to Ordovician limestone karstic water should give priority to the ＂prevention＂. |
