The invention provides a strip type
coal mining method in roof
cutting filling close-to-gob areas. The strip type
coal mining method comprises the following steps: when the size of strip mining is smaller than a direct roof
cutting secondary caving step L0, remaining no caving of a roof plate, firstly adopting small strip
coal pillars, and maintaining large strip coal pillars, wherein the ratio ofextraction to the reservation of the small strip coal pillars to the large strip coal pillars is 1: 2; forming open-off cuts in the small strip coal pillars, mining remaining small strip coal pillarsin a drawing-back mode when the small strip coal pillars reach an upper gate road, forming roof
cutting shot holes in two boundaries of the small strip coal pillars along the upper gate road, miningthe small strip coal pillars, and beginning hole firing and roof cutting from the upper gate road; after the small strip coal pillars are mined completely, mining the nearby large strip coal pillars on one side of the small strip coal pillars, cutting off small strip coal to
cut broken waste rocks obtained from an immediate roof, filling while mining until the mining is completed. The suspended size of the roof plate is remained to be smaller than the distance of first roof caving all the time, the top plate does not
cave, and the shoring is relatively simple and safe; the dimension in a goafplane is decreased by about 4 / 5, the ground surface settlement can be effectively controlled, and the method is hardly of destructive effect for the environment.
