| 摘 要： | 根据密集群建筑物下首采区煤层赋存的特点，确定采用条带开采采煤方法，同时，采用概率积分法，研究了不同回采率和采煤方法对地表移动特征的影响，采用超高水材料充填开采回收条带煤柱的方法，提高了煤炭资源回采率，为其它类似矿井提供借鉴。

| Abstract: | According to the deposition characteristics of the coal seam under dense buildings, a new strip fill-mining method has been applied. In the meantime, the probability integral method was employed to study the influence of different recovery rate and mining methods on the earth surface movement. The recovery rate has been improved with the method elaborated on in this paper, which is also a good reference for similar coal mine shafts. |
