摘要
通过对锚杆技术的研究及现场应用表明 ,对不同的地质条件采取不同的锚杆支护方式对支护效果和施工进度有很大的影响 ,如大倾角煤层、窄煤柱护巷、复合顶板、“三软”煤层等困难条件下的煤巷锚杆支护 ,文中就此提出了锚杆控顶技术的研究及应用。
The study and application of bolt support technol ogy show that adopting different bolt support way according to different geolog ical conditions has great effect on support result and construction speed,such a s large inclined coal seam,narrow pillar support roadway, compoond roof,“three soft”seam ect.coal roadway bolt support under difficult conditions.
