为解决中远距离煤层群的煤与瓦斯开发难度大的问题,以阳煤五矿为研究对象,基于现场煤层、瓦斯基础参数,研究了煤层及瓦斯赋存特征,从煤与瓦斯开发在时空层面的矛盾性和同一性着手,分析煤炭开采和瓦斯抽采的相互影响,研究煤与瓦斯协调开发的时空关系,以阳煤五矿的煤与瓦斯协调开发现状为基础,提出采前预抽与采中卸压抽采在时间和空间上的衔接是中远距离煤层群煤与瓦斯协调开发需要解决的关键技术,借鉴晋城矿区"三区联动"模式,探索得到了中远距离煤层群煤与瓦斯协调开发模式,并在阳煤五矿进行示范,以期为相似地质条件煤矿的安全高效生产提供技术支持。

in order to soive the difculty of coal and gas development in the medium and long distance ceal seam group.taking Yangquan No. 5 Mine of the study object.based on the site seam.gas basic paramneters the seam and gas depositin featues weredefned. From the contradiction and identtyof the ceal and gas developmen in the time-space aspects thepaper analyzed the mutual ifuences between coal mining and gas drainage The paper studied the time-space relationship of the .oal and gascoordinated develogmen, based on the coal and gas cordinated develogmert status in Yangquan Na 5 Mine,the paper provided that the time and space .onnection betwieen the gas pre-drainage before the mining operation cnducted and the pressue released gas drainage during the mining percd woul be the key technology to be solved for the coal and the gascoordinative development in the mediun and long distanceseam grou . wih the referencesofthee block linking node inJincheng !Mlining Area.the coal and gas coordiative development modeof the medium and long distance seam group was discovered and obtained.T'he demo of the development mode was conducted in Yangquan No.5 Mine,so as to provide the techrical supor to the safty and high eficient prodvction for sinilar geologcal condti.n.
