锦界煤矿涌水水源主要来自风化基岩孔隙裂隙潜水和第四系上更新统萨拉乌苏组潜水含水层,结合近年大量观测数据,确定回采工作面(含准备面疏放水)及采空区涌水占矿井涌水量的95%以上,是矿井涌水量预测关键所在,利用钻孔流量实测数据的回归分析,得到了钻孔流量衰减特性及其计算公式,并分类计算工作面回采涌水量,并与现场实测结果进行了验证,实现了矿井涌水量快速、精准预测。在此基础上利用研究结果对工作面排水系统进行优化和改进,采用分区关联排水技术,极大地提高了排水系统运行效率。
The gushing water in Jinjie coal mine mainly comes from the pore fissure subduction of weathered bedrock and the aquifer of Salauwesu Formation in the Quaternary Upper Pleistocene. Combining with a large number of observation data in recent years, the working face (including prepared surface draining water) and the goaf The gushing water accounts for more than 95% of the mine water inflow, which is the key point of mine water inflow forecasting. Based on the regression analysis of measured data of borehole flow, the attenuation characteristics of borehole flow and its calculating formula are obtained, Field test results with the validation, to achieve a rapid mine water inflow, accurate prediction. On this basis, the research results are used to optimize and improve the drainage system of the working face and to adopt the partition-associated drainage technology, which greatly improves the drainage system operation efficiency.
