Abstract

The invention relates to the technical field of coal mining, and particularly discloses an ultra-thin coal seam mining method. The method includes the steps of step one, arranging a long-wall retreating type coal face; step two, mounting a diamond bead stringing rope main machine; step three, mounting a guide part; step four, mounting a diamond bead stringing rope; and step five, starting the diamond bead stringing rope main machine. The ultra-thin coal seam mining method aims to solve the problem of mining a coal seam with the thickness of less than 0.8 m.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a method for mining extremely thin coal seams. Background technique [0002] Thin coal seam reserves account for 20% of my country's total coal reserves, reaching 6.15 billion tons, and extremely thin coal seams below 0.8 meters account for 13.98% of my country's total coal reserves. At present, the proportion of thin coal seam mining in my country is only 7.32%. The rate is less than 5%. For a long time, due to the extremely thin coal seam has been greatly restricted in equipment capacity, installation, maintenance, and operation, the problems of low output, high cost, and high labor intensity in the production of extremely thin coal seams have not been effectively resolved. Many coal mines Can only give up the mining of the extremely thin coal seam below 0.8 meters, which greatly wastes the national coal resources. [0003] In recent years, with the reduction of thick and ...
