矿柱强度理论在群采空区稳定性分析中的应用

Pillar Strength Theory in the Application of the Group of Goaf Stability Analysis

根据采空区三维激光精密探测结果和3DMine矿业软件采空区建模数据,采用较为广泛的矿柱强度公式以及面积承载理论计算矿柱强度和矿柱载荷,求得留存矿柱的安全系数,据此评价采空区内留存矿柱的整体稳定性,并判断采空区的稳定性和安全隐患,对同类矿山采空区调查分析有借鉴意义。

According to the result of mined-out area of 3 d laser precision detection and 3dmine goaf modeling data mining software, with wider pillar strength formula and area and pillar load carrying theoretical pillar strength, get the safety factor of pillars, on the basis of evaluate the overall stability of the retained pillar in the mined-out area, and to assess the stability of mined-out area and hidden danger, it is reference significance for similar mine goal survey analysis.
