摘要
通过对下组煤-400m水平1160采区首采面进行十三灰含水层疏降试验,进一步查清了影响下组煤16上煤层开采的水文地质条件,为制定经济、合理、有效的防治水方案和措施提供可靠依据,同时也为全井田下组煤承压水上安全开采提供了防治水经验。
The 13 grey aquifer’ s hydrophobic drop test is done in the first coal mining face of 1160 mining ar-ea, which is minus 400m in the lower coal group.The hydrogeological condition , which affects the mining of upper coal seam in the No.16 lower coal group , is found out.It provides reliable basis for the constitution of economic , reasonable , effective measures of water disaster ’ s prevention and control , and provides experience of water disaster ’ s prevention and control for safe mining on confined waters in the lower coal group of the whole shaft area.
