131矿体采空区顶板稳定性研究

潘洛铁矿洛阳采区矿石及围岩均属稳固类型，开采方法采用空场法。随着采矿的深入，空区安全隐患逐渐暴露。利用计算机数值模拟分析，结合131矿体坑采空区情况，给出稳固性初步评价，为合理选择空区处理方法提供依据。

Study on Roof Stability of Mined-area in No.131 Orebody

The ore and surrounding rock in Luoyang mining area of Panluo Iron Mine are of stable type, where open stoping method is adopted. With the deepening of mining, the hidden dangers in the safety of mined area is gradually exposed. By the computer numerical analogue analysis and in combination with the conditions of the mined area in No. 131 orebody, a preliminary assessment of stability is made, providing a basis for the rational selection of the treatment method of mined area.
