摘　　要："三软"煤层这一现象在煤矿公司企业的挖掘的过程里面总是会遇到,因为这样的煤层,属于是在裂隙的发育,并且这种煤层所处的地理环境组成特别的繁杂,"三软煤层"指的是软弱煤层,即顶板岩层、软主煤层,和底板岩层。所以施工的人员在沿空掘巷施工的操作的过程里面,施工人员要十分的小心谨慎,本篇文章的主要研究内容就是煤矿开采过程中的支撑保护技术和工艺。In the process of mining companies and enterprises in coal mines,the phenomenon of"three soft"coal seams is always encountered.Because this kind of coal seam belongs to the development of fissures,and the geographical environment of this kind of coal seam is particularly complicated."Three soft coal seams"mainly include roof strata,soft main coal seams and floor strata which are all weak coal seams.Therefore,in the process of gob-side entry tunneling,the construction personnel should be very careful.Therefore,this article will explore the specific supporting and protecting construction technology.
