摘要
随着易采煤炭资源的日益枯竭,开采"三下"压煤显得非常急迫,如何在保证建筑物、基础设施等安全运行的前提下,合理地进行煤炭资源的开发是一个非常现实的重大课题。以郑家庄煤矿开采为例,在已有研究成果的基础上,首先采用自行研发的ROCK MODEL程序建立三维地质模型;然后采用概率积分法和数值模拟方法对多个开采方案进行分析计算,在综合考虑文物保护、地质条件、开采设计等因素的基础上,确定出最佳开采方案;其次采用综合研究手段,对采场上覆"两带"发育高度、断层、采动裂缝对近地表浅层含水层疏干和名树古木存活的可能性进行详细论证;最后提出具体防治措施。
As the easily mining resources are being increasingly depleted, it is very urgent to mine coal under buildings, water-bodies and railways. The rational exploitation of coal resource under the premise of the security of constructions and infrastructures etc. is a major practical problem. Taking Zhengjiazhuang colliery for example, based on former research results, a 3D geological model in the study area has been firstly established by the ROCK MODEL software which is developed by authors. Secondly, several mining schemes have been analyzed by probability integral method and numerical simulation method; and the optimal mining scheme is chosen on the basis of synthetical factors such as protection of cultural relics, geological conditions and mining designs etc.. Then the impacts of ＂two-zone＂ developing height overlying the mining face, the faults and mining fractures on the drainage of shallow aquifer near the surface and survival of famous and ancient trees have been analyzed by synthetical methods. Finally, specific protection measures are proposed.
