煤与瓦斯突出，一般多发生在掘进工作面，采用沿空留巷无预掘下顺槽前进式开采方法，杜绝了在原生煤体中的掘进工作，最大限度减少了石门揭煤，充分利用了采场前方的卸压带，达到自我保护的目的。这是单一突出煤层开采的新途径新工艺。图２，参２。 Coal and gas outburst generally occur in the heading face, using pre-excavation of gob-side entry retaining technology along gob-side entry, eliminating tunneling in primary coal, minimizing crosscutting and fully utilizing A pressure relief belt in front of the stope, to achieve the purpose of self-protection. This is a new way to highlight the new coal seam mining new technology. Figure 2, reference 2.
