摘要
分析了母杜柴登首采工作面主要充水水源为顶板砂岩含水层,通过放水试验获取含水层的渗透系数,在此基础上,采用干扰井群的叠加原理计算了首采工作面内部的疏干水量,并根据计算确定了顶板疏放水钻场的最终布置方式,为计算工作面内部疏干水量提供了一种新的思路。
According to analysis, water filling source of the first mining face roof in Muduchaideng Coal Mine was sandstone aquifer. The permeability coefficient was obtained through underground dewatering test. On this basis, the drainage water yield in the first mining face was calculated based on the superposition principle of the interfering well group, according to which, the final arrangement of the roof water drainage drilling field was determined. The study provided a new way of interior drainage water yield calculation.
