煤矿综采工作面煤壁片帮是制约综采效率和工作人员安全的主要因素。现在,生产中普遍采用护帮板来改善煤壁片帮问题。主要针对实际生产中护帮板出现的问题进行理论分析及有限元计算,找出原因,并对护帮板结构提出了改进意见,以达到护帮板结构优化的作用。 Coal mining face of coal mining face is the main factor restricting the efficiency of fully mechanized mining and staff safety. Guards are now commonly used in production to improve the problem of coal wall tiles. Mainly for the actual production of the help board problems appear in the theoretical analysis and finite element calculation to find out the reasons for the board structure and proposed improvements to improve the board structure in order to achieve the role of help.
