基于板破坏理论的条带开采中采宽的确定

Determination of Mining Width in Strip Mining Based on Plate Failure Theory

摘要: 为了确定赵庄二号井煤矿“三下”压煤回采的条带开采尺寸，在保证安全的前提下尽可能多的解放呆滞煤量。以试采区为例，在确定关键承载层的基础上通过Marcus修正简算式和RFPA数值模拟相结合的研究方法对条带开采中的采宽进行分析研究，在试采区实施了条带开采，并对地表沉陷进行了实测。

Abstract: In order to determine Zhaozhuang No.2 Coal Mine strip mining size in "three unders" coal seam and liberate sluggish coal as much as possible under the premise of guaranteeing safety. The paper takes trial mining area for example, using the fixed Marcus simple formula and the RFPA numerical simulation to analyze the mining width of strip mining on the basis of determining key loading strata, apply strip mining in the trial mining area, and measure surface subsidence.
