摘 要:在建筑物下开采深部压煤通常采用条带开采法控制地表移动变形量,条带开采工作面倾斜方向容易形成极不充分工作面,结合某煤矿建筑物下深部压煤条带开采试验,深入研究和探索深部条带开采采宽和留宽确定方法及其协调关系,并与下沉系数法、压力拱计算值法相比较,得出该煤矿条带开采的参数,试验结果表明,极不充分开采法确定开采宽度对于条带开采设计是十分有效的,能有效地控制地表移动和变形程度.本方法对于指导相似地质条件下开采建筑物下压滞的大量煤炭具有较大的实用价值和指导意义.The pillar mining is usually used in the mining under buildings to control extent of the surface movement and deformation. With the increasing depth of mining exploitation, it's apt to reach the super - subcritical exploitation which can cause the insufficient working face. The pillar mining forms super - subcritical exploitation face. By integrating a pillar mining experiment which operates on one coal mine under the building, with the investigation and exploration of the methods of determination mining width in deep strip pillar mining, and comparing the submersion coefficient method and the pressure arches the predicted value method, the strip pillar mining parameter of the coal mine is obtained. The experiment result indicates that it is extremely effective for determination mining width deep strip pillar mining, and it can control the surface movement and deformation sufficiently. The method is valuable to guide the exploitation of the abundant mine under buildings or the similar geological condition.
