煤岩物理力学性质对煤与瓦斯突出的影响研究

煤与瓦斯突出是煤矿中一种极其复杂的动力现象,危害到煤矿生产和人员安全。煤与瓦斯突出的发生机理十分复杂,影响因素众多,其中煤岩物理力学性质是其灾害发生的主要因素之一。随着煤炭开采的发展和浅部可采储量的逐年减少,深部开采成为我国大部分煤矿必须面临的问题,同时煤与瓦斯突出灾害越来越严重,通过煤岩物理力学性质实验室测定可以分析研究煤与瓦斯突出发生前后岩体变形破坏规律。

Effect of Physical and Mechanical Properties on Coal and Gas Outburst

Coal and gas outburst in coal mines is an extremely complex dynamic phenomena,and endangers the safety of coal production.The occurrence of coal and gas outburst mechanism is very complicated,has many factors,in these physical and mechanical properties of coal is one of the main factors.With the development of coal mining and shallow recoverable reserves decline every year,the deep coal mining have become the problems must be faced with the coal mines,at the same time coal and gas outburst is more and more ...
