摘要
为解决10202综放工作面侧向支承压力对相邻工作面巷道影响,通过工作面围岩赋存特征分析和FLAC模拟计算不同煤柱宽度、切顶角度、切顶高度下侧向支承压力分布,确定10202工作面切顶深度24 m、角度0°比较经济合理。
In order to solve the influence of lateral abutment pressure of the 10202 fully mechanized top coal caving face on adjacent working face roadway,the distribution of lateral abutment pressure under different coal pillar width,roof cutting angle and roof cutting height was calculated through analysis of surrounding rock occurrence characteristics and FLAC simulation.The cutting depth of the 10202 working face is 24 m and the angle is 0°,which is more economical and reasonable.
