Based on the previous achievements,the effect of mining subsidence on the safety of the dam,the possibility of leakage and rapid drawdown of water level in the reservoir by mining pressed coal and the influence of mining pressed coal on the seepage field were investigated by the synthesis method combined with field-survey,indoor-test and numerical simulation.
在前人研究成果的基础上,采用现场调研、室内试验、数值计算相结合的综合方法,研究了开采沉陷对大坝安全的影响、压煤开采引发库区渗漏及库水位骤降的可能性及对库区渗流场的影响。
According to the conditionof the geology structure in Qianling district and the situation of the building on the ground,Two mining-methods about pressed coal in villages are putted.
根据前岭煤矿地质条件和地面建筑物情况,提出了两种村庄压煤开采方案,对两种开采方案从技术、经济角度进行论证、分析,确定了全采搬迁方案。
