锡矿山是一个已有90余年开采历史的老矿。于1965～1971年曾发生三次大面积地压活动。为监视采空区的稳定性,从1971年到1980年进行了岩石应力测量和岩体力学的综合研究。本文阐述了岩石应力测量方法和充填后的应力测量情况。研究结果使该矿获得很好的开采技术经济效益。
Tin mine is an old mine that has been mined for more than 90 years. In 1965 ~ 1971 there have been three large-scale underground pressure activities. To monitor the stability of the goaf, a comprehensive study of rock stress measurement and mechanics of rock mass was conducted from 1971 to 1980. This article describes rock stress measurement methods and post-filling stress measurements. The results of the study made the mine a good mining technology and economic benefits.
