Research and Application of Integrated Equipment for Efficient and Intelligent Mining of Thin and Extremely Thin Coal Seams
Abstract：Thin coal seams are widely distributed in more than 80 coal mines in China, with a total reserve of about 9.83 billion tons, of which the recoverable reserves are about 6.5 billion tons, accounting for about 20% of the country's total recoverable coal reserves. However, the technical maturity of mining equipment for thin and extremely thin coal seams is low, the labor intensity for workers is high, the mining investment is high, and the efficiency is low, leading to the general abandonment of thin and extremely thin coal seams, causing a huge waste of coal resources. The output of thin coal seams accounts for only about 10% of the country's total coal production, which is not in line with the recoverable reserves. Efficient and safe mining of thin coal seams is an important way to improve the coal resource recovery rate and alleviate the resource shortage. The development of efficient mining equipment for thin and extremely thin coal seams and the technology of unmanned intelligent mining is the only way to solve many problems in the mining of thin and extremely thin coal seams.
