Abstract

A method for pre-evaluation of coal body gas by establishing evaluation unit before backstopping of working face is introduced. Take #4308 fully mechanized caving face of Chengzhuang Coal Mine as an example, the process of pre-evaluation of its coal body before backstopping and the production capability of backstopping process are analyzed. The findings will lay foundations for future performance evaluation of gas extraction before backstopping of working face, gas control during backstopping and overall planning and linking of extraction and mining in the mining area.
