Description
Technical field
This utility model relates to coal face hydraulic support, is specifically related to a kind of gob side entry retaining support group.
Background technology
Traditional coal-mining method reserved coal pillar between coal-face, coal pillar width commonly reaches 20～25
Rice, loss of coal pillar accounts for more than the 10% of China's coal-mine exploitation losses, as a example by 2014, China's coal-mine
Annual production 38.7 hundred million tons, then be up to nearly 400,000,000 tons because of loss of coal pillar；Meanwhile, gob side entry retaining can realize Y
Type ventilates, and reduces the explosion accident that gas exceeding limit occurs.
At present, the spoil of erecting dense individual props kept out by China's gob side entry retaining commonly used wood point post, for workmen
Operation and pour body of wall space for the creativity, when gob side entry retaining is carried out in the coal seam more than 3 meters, wood point post cost is high,
Difficulty of construction is big, quantities is big, and wood point post can not effectively keep off cash, easily topples over, jeopardizes operating personnel
Personal safety.Common face end support back timber rear portion is short, it is impossible to the personnel of shielding rear operation, to this end, need
Will lapping before frame, but before face end support frame, lapping affects coal-winning machine coal cutting, affects coal production, therefore
Need to change lapping after frame into, it is ensured that operating personnel's safety；Meanwhile, gob side entry retaining needs tunnel to remain,
Needing to protect roof timbering not to be damaged, then need not in the case of not gob side entry retaining, common termination is propped up

Anchor cable, reduces support cost.Therefore, gob side entry retaining needs to realize following target: first, solves to stay along sky
Lane mechanization gear cash, meet supporting intensity requirement, problem that support can move；Second, solve common end
Head bracket afterbody large area sky top exists supporting potential safety hazard, common end head bracket can not protect top board anchor cable,
The problem that before frame, lapping affects coal production；3rd, solve gob side entry retaining face end support and keep off cash with gob side entry retaining
The mutual corresponding problem of support, prevents from leaking between two stands cash, it is ensured that job safety.
