Combining with the present situation of mine mining and the occurrence characteristics of coal seam, different mine field division schemes were put forward. According to the merits and demerits of various schemes and relevant normative requirements, the optimum disk division mode of minefield was settled. On the premise of guaranteeing that the mining principle of "one mine shaft and one coal mining face", new purchase of a set of fully mechanized mining equipment, not only satisfied that the original mine equipment not abandoned, but also reduced its loss, realized continuous jump mining between two different roadway, reduced the influence of mining dynamic pressure on driving roadway, and provided conditions for the follow-up mining resources to the maximum reasonable and efficient condition.
