Abstract: According to the geological features of protective marginal coal pillar under the dongping village, the feasibility and adaptability of the mining of marginal coal pillar by using the short wall mining technology of continuous coal mining machine were analyzed. According to the regional conditions of the first mining face, the technical scheme of the mining method is designed, including the roadway layout, mining process, mining matching of the working face, ventilation system. The practice shows that the technology of short wall mining has achieved good economic and social benefits in dongping coal mine, which provides valuable time for the sustainable development and diversion of production.
