节理频率预测的新方法

A New Method of Counting and Forecasting the Frequency of Joints

针对节理对煤矿生产的影响.本文提出一种预测煤层及其顶板节理频率的新方法。利用这种方法,可以定量预测煤层及其顶板在各个方向上节理频率的数值。使采区和工作面的设计者.能够更加合理地布置巷道.或工作面的采掘方向,以保证安全生产,提高采掘效益。本文利用这种方法,对四川省华蓥山矿务局李子垭煤矿的煤层顶板稳定性作了预测。

To counter the effects of joints on the production of coal mine, the paper advances a new method to forecast the frequency of joints in coal bed and its roof. The frequency of joints in all directions may be forecaset quantitatively by the method. Therefore, designers may better choose the mining and driving direction of coal face and tunnel. The method has been used to forecast the stability of the roof of coal bed in the Liziya mine.
