Abstract

In one embodiment, the invention discloses a gob-side entry retaining method without influence on coal mining procedure, relating to the technical field of coal mining. The method can effectively avoid interference on the coal mining procedure of stope surface. The method includes a step of arranging at least one row of pillars in advance along the advance direction of the coal working surface atone side being closed to the coal working surface in a belt crossheading, which serves as gob-side entry retaining. The method is suitable for roadway and tunnel engineering and coal mining.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a gob-side entry retaining method that does not affect the coal mining process. Background technique [0002] Gob-side entry retention refers to the use of certain technical means to strengthen support or special support means for the trough of the previous coal mining section, and leave it for the next coal mining section. The application in it can maximize the recovery of resources, avoid the loss of coal body, reduce the amount of roadway excavation, and alleviate the alternating relationship between coal mining and excavation. [0003] The existing gob-side retaining method is generally to support the support body on the side of the goaf or goaf as the mining face advances. Interference in the coal process is not conducive to the advancement of mining work and the management of the roof. Contents of the invention [0004] In view of this, the embodiment of the present...
