摘要
麦垛山煤矿130602工作面顶板赋存有2煤顶板含水层、2-4煤间含水层和4-6煤间含水层,为了确定130602工作面受到煤层顶板复合含水层威胁程度的大小和工作面的充水因素,从而有针对性地采取防治水措施,采用关键层理论分析、数值模拟和相似材料模拟3种方法预测130602工作面导水裂缝带发育高度,确定工作面在回采过程中的主要充水含水层,在此基础之上计算工作面涌水量以及制定相应的防治水措施。
There are aquifer above 2#coal,aquifer between 2#and 4#coal,aquifer between 4# and 6# coal on 130602 working face of Maiduoshan coal mine. In order to determine the threaten degree of 130602 working face by the compound aquifer and water disaster factors of 130602 working face,thus the specific measure will be taken. The theory analysis of key strata,numerical simulation and similar material simulation were adopted to predict fractured zone height of 130602 working face,then which is the main threaten aquifer can be determined,on these bases,the water inflow can be predicted and the prevention measures of water disaster can be formulated.
