Embodiment Construction

[0015] A highly mechanized mining method for a thin coal seam continuous miner includes the following steps:

[0016] S1~ Carry out the overall layout of the roadway. First, divide the mining area on the side of the transport lane 1 and the return air lane 2 into several sections, and each section is arranged with three main roadways, namely the middle transport channel 4 and the return air Downward channel 5 and return air downward channel 6, return air upward channel 5 and return air downward channel 6 across transportation lane 1, and connect them through short branch lane and cut-off branch lane 8, forming "one in two "Y" type full air pressure ventilation system; all branch roads adopt anchor belts and mesh cables for permanent roof or help, and the short branch roads excavated in advance to be mined adopt temporary wind control curtains for air adjustment. The mining tunnel 10-1 is opened from the side of the central transportation along the trough 4, and the cutting head o...

Abstract

The invention belongs to the application field of coal mining equipment and a coal mining method, and specifically relates to a highly mechanized mining method for thin coal seam by a continuous miner. The problems of staff reduction for enhancing efficiency and safety mining of current thin coal seam mining are solved. The method of the invention comprises the following steps: S1, overall arrangement of roadway; S2, crossheading and short branch tunnel drilling; S3, long mining and extraction. Without entering the extraction area, the mining efficiency and safety of the thin coal seam are greatly improved.

Description

Technical field [0001] The invention belongs to the application field of coal mining equipment and coal mining methods, in particular to a highly mechanized mining method for thin coal seam continuous miners. Background technique [0002] At present, the short-wall mechanized mining technology led by continuous shearers is being promoted from the Shaanxi and Mongolia mining areas to other mining areas with suitable conditions across the country. In particular, the complete set of continuous mining equipment has been localized, and the performance of the equipment has been continuously improved and stabilized. Great progress has been made in reliability and reliability, and it has completely replaced imported equipment. This series of developments has not only lowered the threshold for mining companies to introduce continuous mining equipment, but also made some of the corner coals, residual coal pillars and irregular sections. Mining troubled small mines, integration and merger m...
