摘要
为探明江西省广丰区某滑石矿区的水文地质参数及矿井涌水量,设计了一个抽水试验孔,并根据抽水试验数据,分别采用数值解析法和现场监测法对水文地质参数进行了估值和矿坑涌水量预测。研究结果表明,数值解析法得出渗透系数K为1.185 m/d,矿层下部含水层厚度M为28.0 m,最终预测矿坑涌水量Q为1038.8 m^(3)/d。现场监测法动态监测得到两处老窿的合计涌水量为1188 m³/d。两组矿坑涌水量数据表明通过数值解析法和现场监测法预测的结果基本一致,说明根据抽水试验和数值解析法获得的水文地质参数较为准确,可为今后矿区的水资源管理和开采计划提供重要数据依据。
In order to investigate the hydrogeological parameters and mine water inflow of a talc mine in Guangfeng County,Jiangxi Province,a pumping test borehole was designed and the hydrogeological parameters were estimated and the mine water inflow was predicted based on the test data using numerical analysis and in-situ monitoring methods.The study showed that the numerical analysis method yield a permeability coefficient K of 1.185 m/d,an aquifer thickness M of 28.0 m in the lower part of the ore body,and ultimately predicted the mine water inflow Q of 1038.8 m^(3)/d.The in-situ monitoring method obtained a combined discharge rate of 1188 m^(3)/d by dynamically monitored the water discharge conditions of two old shafts.The two sets of mine water discharge data indicate that the predictions obtained using numerical analysis and in-situ monitoring methods are basically consistent,which suggests that the hydrogeological parameters obtained through pumping test and numerical analysis are accurate,and can provide important data support for future water resource management and mining plans.
