西曲矿28303工作面措施巷扩帮方案的优化

Optimization of Side Expanding Scheme of Measure Roadway in 28303 Working Face of Xiqu Coal Mine

为了解决西曲矿28303工作面措施巷扩帮期间顶板压力大、围岩破碎、安全系数低、支护困难等问题,通过数值分析、工程类比等方法,优化了28303工作面措施巷扩帮方案,经过现场实践,取得了良好的效果,对西曲矿类似地质条件工作面施工具有重要的参考价值。

In order to solve the problems such as high roof pressure,broken surrounding rock,low safety factor and support diffi-culty in 28303 working face of Xiqu Coal Mine,this paper optimized the side expanding scheme of the measure roadway in 28303 working face through numerical analysis,engineering analogy and other methods.Through field practice,it has achieved good results.This scheme has important reference value for working face construction with similar geological conditions in Xiqu Coal Mine.
