摘要

考虑某典型煤矿特殊地质条件，采用ANSYS建立二维有限元模型，对于断层存在情况下煤柱的合理留设进行了数值模拟计算。分析了留设不同断层保护煤柱情况下开采对工作面前方煤柱及断层的影响，并对开采区顶板的支承压力进行了模拟，提出了断层保护煤柱的合理留设长度，为实际开采提供了可靠的科学依据。

Abstract

Based on the geological and mining condition of a certain coal mine

the two-dimensional finite element model is established by ANSYS

then the rational protective pillar of fault is numerically simulated.The influence of coal and fault in front of working face is also simulated by exploitation under different protective pillars. Through analyzing the abutment pressure of upper floor of coal layer is simulated; and the rational protective pillar is gained. Scientific basis is provided for practical exploitation.
