Today during the mining process in contiguous seams, there are many factors leading to hidden danger, such as: the top board being tortured during the exploitation of the lower seam; the boards of the face and lanes prone to be collapsed and leak which may even cause the curbing collapsing; the serious air leak in mining face.

Layout of actual mining roadways in very contiguous seams;

Roadway support at nearby seams in Wangcun mine;

Forecast Model of Spontaneous Combustion in Goaf of Close Distance Coal Seams;

Taking the first coal face 13116 of the below 6# coal seam in Xieqiao Coal Mine as an example,the paper analyzes the regularity of strata behavior of fully mechanized working face,the law of overburden strata movement,the performance and adapt ability of hydraulic support through observing the pressure appearance in the course of the mining for close distance coal seams.

Under the condition of close distance coal seams ascending mining in Suncun coal mine,using RFPA numerical analysis software,we analyzed the stress environment of the upper coal seam.

The special strata in the faces at close-distance seams are concluded,the technical scheme and characteristics of new-type support equipment used under special geological conditions are introduced.

Drawing test in fully mechanized working face with sublevel caving after mining the up-seam of contiguous seams;
