玉石洼铁矿采场地压控制方法与巷道支护优化

玉石洼铁矿采矿科技攻关中为了防止采场巷道发生破坏，保证正常生产，一方面在总结采场地压活动规律的基础上，提出了地压控制方法；另一方面在强化支护的基础上，提出了优化支护方案。实践表明，上述措施是有效的．本文对这些工作进行了总结．

Control Method of Underground Pressure in Mining Area and Optimization of Drift Supped in Yusbiwa Iron Mine

o protect the drift in mining area against disruption and to prove the normal production,on the one hand,on the basis of the summary of underground pessre active regularity,the controlmethod of underground pressure has put forward on the other hand on the basis of strenthening supportthe optimization scheme of support has put forward. The practice is shown that above mentioned measures are effective. This paper sumed up these works.
