摘要
九龙矿152下07轻放工作面上巷,埋深达700多m,断面9.36m2。本文根据顶板岩芯结构特点,选择大间排距高强度锚杆支护参数进行试验研究,试验巷道经历了静、动压的考验获得成功,取得了良好的技术经济效益。
Abstract
The upper roadway of 152-07 panel lay at a depth of over 700m and had a cross-section area of 9.
36m2. According to the structural features of roof cores, an experimental study on large distance
spaced rock bolts of high strength was conducted. This trial proved successful after the tried
roadway had been experienced tests of static and dynamic ground pressure and an excellent
economical result had been achieved.
