摘    要: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。

关 键 词:地压控制  急倾斜破碎富锰矿体开采  三维有限元

Abstract:With investigation on the underground pressure in situ and numerical analyses of B-D FEM, this pa-per describes the activity rules of underground mining pressure in the xiaotianjing's Mining on break-steeply dipping high-grade manganese ore body of Heqing Manganese Group.taking the controlling teehniques of un-derground mining pressure such as filling exhausted area for blocking fall zone,control stoping layer heighr,con-trol blasting,and extraction sequence from footwall to hanging wall,stoping safety is assured and remarkable el-feets is obtained.
Keywords:Steeply dip  Break  High-grade Manganese ore  Controlling underground pressure
