摘要 根据810采区钻孔及地质资料、相似材料模拟和计算机数值模拟分析,系统分析了该区第四纪水文地质特征、基岩风化带工程地质特征和最大垮落带、最大裂隙带发育特征。并在此基础上结合生产实践,实现了近似使该区防塌煤柱缩小为零后的安全、合理回采,提高了资源回收率,解放了大量的煤炭呆滞储量,从而延长了矿井的服务年限,获得了可观的经济效益。 According to the borehole and geological data of No.810 mining area, simulation of similar materials and simulated analysis by computer, the hydrogeological feature of quaternary, engineering geological feature of mantlerock, growth of maximum caving zone and cracking zone in this area are analyzed systematically. On the basis of these analysis and mining practice, the safe and reasonable extraction is realized in this area after reducing the number of waterproof pillars to nearly zero, reclaiming ratio of resources is improved, and quantity of coal reserves are released. Therefore the term of mining is prolonged and a great deal of economic benefits is obtained.
