Abstract

For the actual implementation of fully-mechanized caving mining in thick coal seam in China, systems analysis of the influence factors of top coal capability, including natural geological factors and technology factors. Influence factors of top coal capability, constitute analysis of fully mechanized caving coal loss, thereby reducing loss of coal, improve mining rate of fully mechanized caving is the urgent need to solve a problem. Reasonable choice of caving top coal caving technology and determine the appropriate parameter is the main measure of improving coal recovery ratio, analysis and solution of these problems in ensuring mine achieve stable yield, high yield, high efficiency, high recovery ratio of main technical means.
