THE RATIONAL EQUIPMENT MATCHING OF COAL MINING AND CAVING SYSTEM IN FULLY MECHANIZED SUB LEVEL CAVING FACE

The rational equipment matching of coal cutting and caving system in fully mechanized sub level caving coal face can make fully use of the capability of equipment, increase the operating rate of capacity and monthly production. Based on the data measured in site, the calculation method of the capacity matching between the front and the rear scraper conveyors is established, and the calculation parameters are determined by the principle of maximum parallel operation in mining and caving processing. The calculating result shows that the main influence factor of the capacity matching between the front and the rear scraper conveyors in the working face is the ratio of the mining and caving height.
