摘要
以屯兰矿18407工作面为例,分析了该工作面的地质和巷道布置概况,分别讨论了两顺槽、切眼和底抽巷的断面尺寸是否满足要求,并对巷道支护中的锚杆长度和间距、锚索长度和间距等重要参数的计算方法进行研究,提出了特殊条件下巷道的加强支护方案,对锚杆、锚索等支护材料的安装技术要求进行了分析,为进一步提高支护稳定性及安装效率提供了依据。
Taking 18407 working face of Tunlan coal mine as an example,this paper first analyzes the geology and roadway layout of the working face,and then discusses whether the cross-section size of two crossheading,cut and bottom extraction roadway meets the requirements,and studies the calculation method of important parameters such as bolt length and spacing,anchor cable length and spacing in roadway support,and then puts forward the design method of roadway under special conditions Finally,the technical requirements for the installation of bolt,anchor cable and other supporting materials are analyzed.
