| 摘 要： | 通过对井田内各地层及断层带富水性的分析,认为井田主要含水层为松子坎组、茅草铺组、夜郎组玉龙山段、长兴组、龙潭组及茅口组;矿井直接充水水源为长兴组岩溶水、龙潭组裂隙水及茅口组岩溶水,间接充水水源为松子坎组及茅草铺组、夜郎组玉龙山段的岩溶裂隙水;充水通道为岩溶裂隙、采动裂隙和断层破碎带;在断层破碎带附近或煤层与茅口组相接部位,易产生突水,要做好超前探放水工作,保证矿井安全生产。

| Abstract: | Through minefield stratigraphic and fault zone water yield property analyses, considered that the main aquifers in the minefield are in Songzikan and Maocaopu formations, Yulongshan Member of Yelang Formation, Changxing, Longtan and Maokou formations. Mine＇s direct recharging sources are Changxing Formation karstic water, Long-tan Formation fissure water and Maokou Formation karstie water; indirect recharging sources have karstic fissure water from Songzikan and Maocaopu formations, Yulonghsan Member of Yelang Formation. Water filling channels are karstic fissures, mining-induced fissures and shattered fault zones. Near the shattered fault zones or contact parts of coal seams and Maokou Formation, are easy to happen water bursting, thus advanced water investigation and drainage are needed to ensure mining safety. |
