六十年代以来,江西省钨矿山共有九矿十个矿区出现过31次较大规模的地压活动。通过我所和其它兄弟院所、有关矿山多年来开展的地压科研工作及生产实践证明,江西钨矿上部开采中段的地区活动是在一定的基本条件下发生的,其主要表现形式多为由开采形成的急倾斜脉群矿山工程结构体,在一定的因素影响下,沿结构弱面向采空区滑移与崩塌;这种滑移与崩塌随时间的变化过程具有一定的规律性。据此,可把地压活动划分为不同的发展阶段,并针对性地采取措施,进行观测预报与控制。
Since the 1960s, there have been 31 large-scale ground pressure activities in ten mines in the nine mines of Tungsten Mines in Jiangxi Province. Through the ground-pressure scientific research and production practice carried out by our institute and other brothers and institutes over the years, it is proved that the activities in the middle section of the upper mining of Jiangxi tungsten ore take place under certain basic conditions and its main manifestations are mostly from Under the influence of certain factors, the steeply pitched mined mine engineering structure formed by mining can slip and collapse along the weak structure of the goaf. The sliding and collapse processes with time have a certain regularity. Accordingly, the underground pressure activities can be divided into different stages of development, and targeted measures to carry out the observation and forecasting and control.
