一、根据煤与瓦斯突出时的 各种现象考察瓦斯突出 的发生机理 1.煤与瓦斯突出机理概要 作者对突出机理有如下看法: (1)煤与瓦斯突出的发生能源是瓦斯,除此而外,别无其它原因; (2)作为突出的发生条件应为如下各点: ①瓦斯在高压作用下,能够破坏煤、岩柱。 ②即使是高压瓦斯,但由于量少而无突出发生。为要突出,高压瓦斯必须集中; ③积聚的瓦斯在突出前要无泄漏; ④瓦斯压力对煤、岩柱应产生有效作用; ⑤煤、岩柱的强度与瓦斯压力的平衡状态被一举破坏。
First, according to the various phenomena of coal and gas outburst phenomenon to investigate the mechanism of gas outburst 1. Coal and gas outburst mechanism summary The author of the salient mechanism has the following view: (1) coal and gas outburst occurs energy is gas, in addition Outside, there is no other reason; (2) as a prominent occurrence conditions should be as follows: ① gas under the action of high pressure, can destroy coal and rock columns. ② Even high-pressure gas, but due to the small amount of non-prominent. In order to highlight the high-pressure gas must be concentrated; ③ accumulation of gas in the outstanding before the leak; ④ gas pressure on coal, rock columns should have an effective role; ⑤ coal, rock column and gas pressure balance of the state was destroyed.
