Study on the Residual Coal Distribution and the Improving Measures

Abstract:

The core problem of fully mechanized top-coal caving technology is to accurately grasp residual coal distribution characteristics and improve the recovery rate to the highest possible. Based on the top-caving working site in some coal mine, combined with the numerical simulation on the residual coal in end roadway, the distribution of residual coal is analyzed. Corresponding improvements on the production system have been proved to be efficient for recovering the residual coal.
