【摘要】 通过对青海省鱼卡煤田尕秀西段的构造特征、地形地貌、水文气象等区域水文地质条件的研究,对矿区供水水源进行初步评价,查明孔隙潜水的允许开采资源量为8.55×104m3/d,矿区水质被评价为合格—微超标,经适当处理,可以满足生活饮用的要求。矿床为裂隙充水矿床,主要充水含水层煤五、煤七顶部含水层富水性弱,单位涌水量q<0.025L/(s.m),地下水补给条件差,水文地质边界条件简单,虽然主要矿体煤五、煤七均位于当地侵蚀基准面以下,但矿体不受地表水体的影响。更多还原

【Abstract】 After analyzed regional hydrogeological condition including structural features,topography and geomorphology,hy-drology and weather in Gaxiu west segment,Iqe coalfield,Qinghai Province,the paper preliminary assessed water supply con-dition of the mining area.Ascertained that the permissive mining yield is 8.55x104 m3/d,water quality is up to grade or slightly go beyond the standard,but can be used as living water after processing.The water filling of the deposit is fissure water filling type.Main aquifers have No.5 coal roof and No.7 coal roof aquifers,they all have weak water yield property,specific capacity q < 0.025l/s·m.Ground water recharge condition is poor,hydrogeological boundary condition is simple.Al-though the main coal seams Nos.5 and 7 are all below the local base level of erosion,but no influence from surface water at all.更多还原
