不同采煤工艺对围岩控制的影响分析

Analysis of Influence of Different Mining Technology on Surrounding Rock Control

为进一步提升煤矿的生产的安全性和开采效率,根据煤矿地质、煤层等条件选择最佳采煤工艺尤为重要。以5401和1405综采工作面为例,在分析其地质及顶板情况的基础上,分别对大采高工艺和综放开采工艺下对应工作面覆岩结构、液压支架载荷以及来压特征等进行对比分析,为后期不同采煤工艺下顶板管理和围岩控制提供参考。

In order to further improve the production safety and mining efficiency of coal mine,it is particularly important to select the best mining technology according to the coal mine geology,coal seam and other conditions.Taking 5401 and 1405 fully mechanized working faces as examples,based on the analysis of their geology and roof conditions,the overburden structure,hydraulic support load and incoming pressure characteristics of the corresponding working face under large mining height technology and fully mechanized top coal caving mining technology are compared and analyzed respectively,so as to provide reference for roof management and surrounding rock control under different mining technologies in the later stage.
