Coal and gas outbursts associated with reverse faults nearly always occurred in the footwalls. Additional data were also used from two mines in Sichuan Province and one in Henan Province. The first important observation of the geological structural phenomena was that coal seams in the footwalls ...
1.Area which abut on faults or other structures is an important part in preventing coal and gas outburst,this paper analysed the work ofgas control and coal outburst preventionin similar conditions,according to the construction practice of No.断层等地质构造带附近是煤与瓦斯突出防治工作的重点部位。
The outburst of this stage is mainly caused by the gas pressure and the increasing stress consolidates the coal. In the second stage, with the increasing stress, the role of the stress shifts from consolidating coal to damaging it. The stress shows the positive effect on outburst: the stress...
