摘要
本文从地质构造的观点出发,阐述不同力学特性地质构造形迹对瓦斯赋存及突出的控制作用;并探讨用地质构造逐级控制的方法,预测与煤和瓦斯突出点相关的小构造,从而预测预报煤与瓦斯突出。
Gas formation, accumulation and movement are closely related to geological structure depositional environment as well as stress conditions.Coal mining activities clearly show that coal and gas outburst is controlled by geological structure. A discussion of some relations between the distribution of gas outburst and structural trace coal layer depth as well as coal occurrence is presented.The results suggest that using stepwise tectonic control to predict coal and gas outburst would be hopeful in practice.
