METHOD FOR DEVELOPMENT OF A SET OF THIN STEEP COAL SEAMS AND APPLIANCE FOR ITS IMPLEMENTATION

摘要

Method for development of a set of thin steep coal seams is in preliminary drilling of well in the area of the mine workings, with feeding through pipeline working liquid by high pressure pumps, and with coal breaking by jet; at that one forms not less than four jets and not less than two of those are directed in parallel to the coal bed along its base and ceiling, and the others are directed at angle to the seam from the base to ceiling and at angle to the seam from ceiling to base, at that the angle corresponds to about 45 DEGREE . Appliance for development of a set of thin steep coal seams has a pressure pipeline, this is connected to a flexible hose winded to a cylinder, and dispenser, and the unit is equipped with two skis, between those telescopic stands are fixed, the dispenser is arranged as a hollow cylinder at the outer surface of which there are placed branch pipes equipped with high-pressure hoses with nozzles, it is installed on the lower ski; at that both skis are equipped with rollers fixed at angle to the axis of the ski, and as a flexible hose one uses a high pressure hose.
