【摘要】 煤炭资源是煤炭企业生存和发展的前提和基础。在国有大中型煤炭企业中,由于建筑物下开采技术不够成熟,村庄下压煤严重制约着煤炭企业的发展。因此解决建筑物下采煤问题,不论是从理论上、技术上,还是经济上,对发展煤炭科技及煤矿生产都有重要意义。本文论述了村庄下采煤在国内外的应用现状,提出了存在的问题,并对优化方法进行历史回顾,列举了日前常用的开采方案优化设计方法,从地面建筑物的防护与治理、减小地表移动与变形的采矿措施和减小地表移动与变形的充填措施三个方面介绍了村庄下的采煤技术,在此基础上,根据地表移动对地面建筑物的影响、破坏程度的不同,构建了村庄下开采方案的优化模型,以艾友矿的课题作为检验方案优化的实例.结合艾友矿地质条件,查阅有关资料,并进行现场实测,通过相应的应用软件对数据进行处理,对所有的可行方案进行检验,以确定较优开采方案,然后利用费用一一效益分析法对较优方案进行经济评价,使其在保证开采对地面建筑物影响程度较小的前提下,尽可能地开采赋存煤炭,达到煤炭采出率最大,经济合理,效益最优。更多还原

【Abstract】 Coal resources are prerequisite and foundation that the coal enterprise survive and develop. In the state large-and-middle scale coal enterprise, because the technology mining under flic building is not ripe enough, the coal pressed under the village restricts the coal enterprise’s development seriously. Therefore, to solve the problem mining under the building have important meaning to develop coal science and technology and to coal production no matter on theoretics, on technology or on economy.This paper described the current situation that the mining under the village was applied home and abroad, put forward the existing problem, reviewed the method of optimizing, listed the design methods of optimizing of mining plan that were in common use now, introduced mining technology under the village from those three aspects, the reinforce and repair of ground building, raining and filling measure of reducing the earth’s surface move and deformation. On the base of this, structured the optimum model for the mining plan under the village according to the earth’s surface move’s impact on ground building and its different destruction degree. Having the task of Aiyou mine as the instance to examine the scheme optimizing, referred to geological conditions of Aiyou mine, consulted relevant materials, surveyed on the spot, processed the data through the corresponding application software, examined all feasible schemes, in order to confirm more excellent mining plan, then utilized the expenses - benefit analytic approach to carry on economic evaluation for the plan, made it base on the premise that exploit with smaller influence degree on the building, exploiting storing mine as much as possible, reach the aim that the coal mining rate is biggest, economy is rational, benefit is optimum.更多还原
