九里山矿底板突水监测预警技术的实践应用

以九里山矿16052工作面为研究对象,采用微震监测技术构建底板突水监测预警系统,并进行实践应用。监测预警结果表明:16052工作面底板总体情况稳定,局部可能发生损伤,底板出水点位置可能位于工作面前50 m至后30 m区域,底板破坏深度约11.38 m,理论计算结果验证了微震监测预警系统结果的准确性。

Practical Application of Floor Water Inrush Monitoring and Early Warning Technology in Jiulishan Mine

Taking the 16052 working face of Jiulishan Mine as the research object,the monitoring and warning system of bottom water inrush is constructed by using microseismic monitoring technology and applied in practice.The monitoring and early warning results show that the bottom plate of the 16052 working face is stable and local damage may occur.The outlet point of the bottom plate may be located in the area of top 50 m to bottom 30 m regions.The failure depth of the bottom plate is about 11.38 m,The theoretical calculation results verify the accuracy of the microseismic monitoring and warning system.
