陈四楼煤矿21109综采工作面底板灰岩水治理技术研究

在水文地质条件相似的情况下,与21109综采工作面临近的21301综采工作面发生了底板灰岩突水事故。通过分析陈四楼煤矿21109综采工作面水文地质条件,实施工作面底板瞬变电磁法勘探探测底板富水异常区,采用底板扰动破坏深度数值模拟及基于BP神经网络的底板扰动破坏深度模型等方法预测了21109综采工作面底板扰动破坏深度,优化设计了底板注浆改造钻孔,杜绝21109综采工作面突水事故的发生,保证了工作面安全生产。

Study of Mechanized Mining Face Floor Limestone Water Treatment Technology in Chensilou Coal Mine

In the case of hydrogeological conditions similar to work with 21109 fully mechanized coal mining face,the limestone floor water inrush in 21301 fully mechanized working face.Chensilou coal mine 21109 fully mechanized working face through the analysis of hydrological and geological conditions,the implementation of the working face floor transient electromagnetic method exploration of water anomaly area of floor,the floor disturbance depth numerical simulation and apical plate based on BP neural network disturbance damage depth model to predict the bottom 21109 fully mechanized working face of disturbance damage depth,optimization design bottom grouting transformation drill,prevent water accidents in 21109 fully mechanized working face of sudden occurrence,guarantees the safety in production of working face.
