Abstract
The article according to the basic parameters of gas,such as gas content,gas pressure,the solidity modulus of coal,gas early speed of diffusion,gas adsorption coefficient,etc,comprehensive analysis of gas geological conditions and the destruction type of coal of Tanyaogou coal mine,with the unit index,comprehensive index method and gas content method,thus the evaluation of outburst danger of 1 940~1 985 m level coal mining in Tanyaogou coal mine,and the results are useful for the production of coal mine and gas outburst in coal mine management to provide a scientific basis for partition.
