摘要
近年来瓦斯抽采成了困扰贵州小型煤矿的主要难题,虽然贵州省已开展多项瓦斯整治项目,但是对小型煤矿瓦斯抽采立项甚少。确定瓦斯抽采现状的影响因素,建立小型煤矿瓦斯抽采现状评价体系,研究评价体系中影响因素的权重值大小并进行排序,对小型煤矿有针对性地改善瓦斯抽采现状具有指导意义。
In recent years, gas extraction has became the main problems of small mines in Guizhou Province. Although many companies have undertaken a number of gas remediation projects in Guizhou Province, there is few research about small coal mine gas extraction. The factors affecting gas extraction current situation are identified, the situation assessment system of gas extraction are established for small-scale mines, and the weights of influencing factors are researched. These have guiding significance for targeted improving small-scale coal mines' gas drainage.
