Abstract

The 367 coal mining face in Fengcheng Shangzhuang coal mine was selected for the project background, the law of the mining permeability is mirrored by the law of the flow of parallel hole that drain gas from virgin coal seam following by the moving of working face. According to the surveying data, the flow of hole had three sections, addition, declining, addition. The permeability of mining coal is mirrored indirect. The main reason was that the mining coal had experienced elastic deformation, plastic deformation, unloading expansion under the procession of coal mining, the permeability of mining coal is changed. It was important to study the law of gas transport, at the same time, it was the theory basis to control the gas effectively.
