地质构造控制煤和瓦斯突出作用类型研究

RESEARCH ON THE TYPES OF GEOLOGICAL TECTONIC CONTROLLING COAL GAS OUTBURSTS

对河南平顶山、安阳和四川南桐、天府矿区地质构造与煤和瓦斯突出的关系研究表明，地质构造控制突出的分布主要有四种作用类型，不同构造具有不同的突出倾向性．提出将地质构造分为突出构造和非突出构造及突出构造的突出段和非突出段，利用地质构造指标预测突出的技术关键是区分突出构造的突出段．

The relation between geological tectonics and coal gas outbursts in Pingdingshan and Anyang mine areas in Henan Province and Nantong and Tianfu mine areas in Sichuan Province was studied. The results show that there are four types of geological tectonics which controll coal and gas outbursts, and that different tectonics have different outburst tendency. The tectonics can be divided into tectonics prone to outburst and tectonics not prone to outburst. And the tectonics with proneness of outburst can again sub divided into outburst section and non outburst section. How to distinguish the section with proneness of outburst within the tectonics prone to outburst is the key in prediction of outburst by using geological tectonic index.
