曹家洼金矿原岩应力测量及其应用
|
摘要
曹家洼金矿进入小尹格庄矿区开采后地压现象非常复杂.为了优化地下开采方法,开展了以应力解除法为主,声发射法作为验证的原岩应力测量,初步掌握了矿山原岩应力分布特征.在此基础上,对现用的上向水平分层胶结充填采矿法结构参数进行了优化,提高了生产效率,强化了采场安全.
The earth pressure of Caojiawa Gold Mine becomes very complicated when the exploitation proceeds to the Xiao-yi-ge-zhuang area.In order to optimize the underground mining method,the original rock stress measurement is implemented,which is on the basis of the stress relieving method and tested by the acoustic emission method,and the original rock stress distribution characteristic is preliminarily mastered.On the basis of that,the structural parameters of the presently used overhead horizontal slicing and cemented filling mining method are optimized,and the mining becomes more efficient and safer.
