Abstract:

Most of mountain coal mine belong to outburst mine in Shuichen, Guizhou, when mining engineering emerge geologic structures like fault, outburst accident tends to happen easily. Taking Miluo coal mine of Gemudi Mining Co., Ltd as the example, a set of construction techniques are taken use to cross faults for mountain coal mines of the medium-thickness coal seam, which gives rise to preferable security effects and promotes excavated rate, thus the first mining face is put to production in advance, and favorable economic benefit is achieved.

Key words: mountain coal mine, geologic structure, haulage entry, cross fault, construction techniques, security effect
