摘要:
瓦斯赋存规律认识不清,是导致煤矿瓦斯突出灾害频发的根本原因。应用瓦斯赋存地质构造逐级控制理论,结合辽宁省煤矿瓦斯地质图编制资料,分析了全省瓦斯赋存构造控制规律,进行了瓦斯分带划分。研究结果表明:印支运动(主幕),在形成一系列EW向、NE向和NW向断裂褶皱带过程中,煤体破坏,形成构造煤。燕山运动,形成了一系列NNE向、NE向的褶皱和逆冲推覆构造,与EW向构造相叠加,构造应力集中,有利于瓦斯突出;同时,岩浆侵入煤系地层使煤变质程度增高,生烃能力增强。喜马拉雅运动时期,挤压作用逐步被拉张取代,拉张裂隙作用有利于瓦斯部分释放。将辽宁省煤矿瓦斯赋存分布划分4个高突瓦斯带,即阜新-铁岭高突瓦斯带、抚顺-沈北高突瓦斯带、北票-南票高突瓦斯带和红阳-本溪高突瓦斯带。
Abstract:
Unclear understanding of the gas occurrence rule is a root cause of frequent gas outburst disasters. Based on theory of gas occurrence tectonic level control, and combining with datum about gasgeology map of Liaoning Province, the tectoniclevelcontrol rule and zonedividing of gas occurrence were discussed. The results showed that tectonic coal formed during the forming of EW, NE and NW faults and folds which were controlled by Indosinian movement. NNE, NE folds and overthrust formed during Yanshan movement, through compounding with the EW geological structure, it caused the tectonic concentrated stress which is prone to coal and gas outburst. At the same time, Yanshanian magmatism increased coal metamorphism and the hydrocarbon productivity of coal was enhanced. During Himalayan movement, tectonic compression was replaced gradually by tectonic extension, which was beneficial to gas release. Coalmine gas occurrence and gas distribution in Liaoning Province were divided into four high and outburst zones, such as FuxinTieling, BeipiaoNanpiao and Hong Yang  Benxi.
