摘要
构造应力是促进煤炭物理和化学变化的主要压力因素,造成地温局部升高,改变煤的结构。地温升高改变瓦斯动力机制,互相叠加后造成瓦斯含量、动力大幅度提高,给煤矿开采带来难度。
The structural stress is the main factor promoting physical and chemical changes of coal, which can cause the local rise of geotemperature. The structural stress can transform the structure of coal and the rise of geotemperature will change the dynamic mechanism of gas, which can superimpose each other and then cause the evident rise of content and dynamic of gas and complexity, difficulty of coal mining.
