济宁二号煤矿六采区压煤村庄搬迁可行性研究

Removal Feasibility of Villages above Sixth Mining Area in Jining No.2 Colliery

村庄压煤问题严重制约着济宁二号煤矿的生产接续与发展。结合该矿六采区的地质采矿条件,针对大郝村、大屯村两个村庄下压煤问题,提出了条带开采法和村庄搬迁后完全垮落法开采两种解决途径。采用概率积分法,预计了两种开采方案对地面建筑物的采动影响,采用条带法开采,虽然能使地面建筑物得到较好的保护,但是经济上的损失巨大。从技术、经济两个方面,综合考虑村庄搬迁法更为合理,并根据具体情况,对村庄的新村选址方案进行了比选。

The development of Jining No. 2 colliery is restricted seriously by the coal mining under villages. Combined with the geological and mining conditions of the sixth mining area, two methods are put forward of the roof caving after relocating the villages and the strip mining in order to solve the coal mining under Dahao and Datun villages. The probability integral method is used to predict the effect which the coal mining has on ground buildings under different mining methods. Although the ground buildings can be protected well by adopting the strip mining method, the financial loss will be huge. Considering the aspects from technology and economy synthetically, roof caving after relocating the villages is more reasonable, and according to specific conditions, the site selection of new villages is determined.
