摘要
分析研究了小窑头煤业公司81201工作面顶板来压规律、液压支架工作阻力分布情况、支架的适应性、超前支承应力分布以及煤壁片帮情况,掌握了工作面矿压显现特征和规律。
Based on the analysis of roof pressure law,the working resistance distribution of hydraulic support,the adaptability of support,the distribution of advanced abutment pressure and coal wall rip spalling at 81201 working face,the author masters characteristics and regularity of strata behavior at working face.
