内蒙古泊江海子矿煤层顶板涌(突)水危险性分区评价
|
摘要
煤层顶板涌(突)水经常给矿井生产带来巨大危害,一直影响煤矿的安全回采。导水裂缝带沟通煤层顶板主要含水层是发生顶板水害的主要因素,随着顶板水害研究程度深入,预测方法在不断改进和完善。在煤层顶板充水含水层富水性弱—中等、含水层沉积厚度大及抽水钻孔少的情况下,对"三图—双预测"法从三个方面进行了优化,分别为数据采集对象、"单"核心变为"双"核心、增加校验过程等,提高了评价方法准确性。运用优化后的"三图—双预测"法对泊江海子煤矿3-1煤顶板直接充水含水层涌(突)水危险性进行了分区评价,预测结果通过了单位涌水量及井下放水试验的验证,其准确性较高。
Coal roof water inrush( bursting) can bring great harm to the coalmine production,impact safe coal winning. The connection of coal roof and main aquifer through water conducted zone is the main factor in roof water hazard. With the deepening of roof water hazard research extent,the prediction methods are improving and perfecting constantly. Under the conditions of coal roof water filling aquifer water yield property weak to medium,large aquifer sedimentary thickness and less pumping boreholes,carried out optimization for the "3 zoning maps plus 2 water inflow predictions"method from 3 aspects including data acquisition object,"single-core"turning into" dual-core"and checking procedure adding,thus to improve assessment accuracy. The zoning assessment carried out through the optimized method for water inrush( bursting) hazard of the coalmine's coal No. 3-1 immediate roof water filling aquifer,the predicted results have tested and verified through specific capacity and underground outflow tests,thus confirmed its higher accuracy
