Ground stress field characteristics and their influence on coal and gas outburst in Qidong well field
摘要
Abstract
Ground stress is the important power of coal and gas outburst, regional stress field is the concrete re-flection of the comprehensive results of tectonic movements of different periods in a region. Combining regional stress and regional tectonic fault block division, the paper studied Qidong stress field and the impact on coal and gas outburst. The results show that the relationship between coal seam depth and maximum, intermediate, minimum principal stress of Qidong well field is positive correlation. Furthermore the maximum principal stress is obviously much greater than that of Jiaozuo Zhongmacun mine, Pingdingshan No.1 mine, No.6 mine, No.8 mine located in North China and Huainan Panyi mine, Xieyi mine located in East China. As Qidong well field is in the high stress region, ground stress is the primary factor of 25 coal and gas outbursts in No.9 seam. The ground stress is concen-trated in the east of the field,and the gas content is very high, leading to the great danger of coal and gas outburst in the region.关键词
