摘　　要：根据煤层瓦斯含量、煤层瓦斯压力、煤的坚固系数、瓦斯放散初速度、瓦斯吸附系数等瓦斯基础参数,综合分析了炭窑沟矿井瓦斯地质条件和煤层破坏特征,采用单项指标法、综合指标法和瓦斯含量法,完成了炭窑沟矿井二4煤层1 940～1 985 m水平工作面采前煤与瓦斯突出危险性评价,为生产矿井防治煤与瓦斯突出管理提供科学依据。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.

关 键 词：瓦斯地质 突出危险性评价 瓦斯含量 瓦斯压力 瓦斯防治
