摘要
以蒙陕矿区葫芦素煤矿2-1煤东翼回风大巷掘进为工程背景,详细介绍了深部高应力矿井永久巷道支护技术与现场应用情况。在深部巷道围岩地质力学测试与评估、可锚性试验、锚杆支护作用机理分析的基础上,提出合理的锚网索支护方案。
Under the engineering background of 2-1 coal seam return-air roadway in Hulusu coal mine, the complete technology in roadway supporting and its practice experiments were described in detail. Based on the results of geo-mechanics test, anchor tests in roadway surroundings, theory analysis of bolting support, some supporting parameters for deep coal mine with high in-situ stress were carried out.
