介绍了云南省鹤庆锰业集团小天井矿区急倾斜破碎富锰矿体开采中 ,通过现场地压调查 ,结合三维有限元数值分析、地压的研究方法 ,揭示了采场地压活动规律 ,采取了充填或隔离冒落区、控制回采分层高度、采场控制爆破落矿和由下盘向上盘的回采顺序等采场地压控制技术 ,保证了采场的回采作业安全 ,效果显著。 This paper introduces the investigation of ground pressure, investigation of the site pressure, numerical analysis of the three-dimensional finite element method and ground pressure in the mining of the sharply inclined fractured and rich orebody in the small courtyard mine in Heqing Manganese Industry Group in Yunnan Province. Filling or isolation of the caving area, control of the mining level, stope blasting and mining and from the next plate to the plate back to the order of mining ground pressure control technology to ensure the safety of mining operations, the effect is significant.
