一种分析条带煤柱稳定性的新思路

A New Thinking To Analyze the Coal Pillar Stability of Strip Mining

为了全面地分析条带煤柱的稳定性，本文采用新兴的复合岩体力学理论，分析了岩体层面效应对煤柱稳定性的影响，发现此种效应可引起煤柱强度提高，从而改善其稳定性。

In order to analyze the pillar stability of strip mining comprehensively,the new method of combined rock mechanics is complied in this paper.The influence of rock layer effect on the coal pillar stability is analyzed,finding the coal pillar strength increased and its stability improved.
