摘要
复杂地质条件下巷道掘进过程中经常揭露松软破碎围岩,穿过断层构造、岩溶裂隙区域。夜长坪钼矿地质条件复杂,在基建过程中,结合顶板分级管理,跟踪管理施工过程,提出超前探水、预注浆、超前管棚、钢拱架等综合支护技术,实现了对复杂地质条件下巷道掘进的地压控制,取得了良好的经济效益和社会效益。
Drivage under complicated geological conditions often reveals soft and broken smwounding rock, and cuts through the fault structure and karst fissure zone. Since the geological conditions in Yechangping Mclybdenum Mine are complicated, during the process of infrastructure construction, Yechangping Molybdenum Mine, by employing classified roof management, tracking and regulating construction process, came up with integrated support techniques including in-advance water detection, preliminary grouting and in-advance pipe-shed and steel arch support, realized ground pressure control in the process of drivage under complicated geological conditions, and achieved good economic and social profits.
