摘要
为了保证综采工作面的安全生产,根据煤层赋存和顶板岩性,分析了支架合理工作阻力确定方法,通过计算选择了采面液压支架,并对顶板日常管理和采面端头支护提出了合理安排。8814工作面综采实践表明:支架运行状况良好,顶板管理措施得当,保证了工作面安全回采。
In order to ensure the safety of fully mechanized working face production,according to the occurrence of coal seam and roof lithology,bracket,and a method for determining the reasonable working resistance are analyzed by calculating chose mining hydraulic support,and the roof of daily management and mining face end support reasonable arrangement are put forward.8814 fully mechanized face practice shows that support running in good condition,roof management measures reasonable,it guarantees the safety mining working face.
