A STUDY ON THE RELATIONSHIP BETWEEN ROCK STRESS AND OUTBURSTS OF COAL AND GAS
-
摘要: 本文以声发射粗估法地应力测量,研究谢二煤矿煤和瓦斯突出与地应力之关系。研究结果表明,煤与瓦斯突出与地应力呈正相关关系。也就是说,凡煤与瓦斯突出地带均属地应力超常地带,而安全地带的地应力值则正常或偏低.Abstract: The relationship between rock stress determined by AE method and the coal and gas bursts in the Xieer coal mine is given in this paper.It shows that the bursts occur in high stress areas,and none in normal or low stress areas.
