Guide: on August 30, the telescopic mast drilling rig derrick, the main part of the first domestic coal seam gas drill locomotive product independently developed by Shijiazhuang Coal Mining Machinery Co., Ltd., won a national patent. During the "1025" period, the development highlight of China's new material industry, 10 foot coalbed methane drilling locomotive is a product developed by the stone coal machinery company in 2009 to fill the domestic gap, which is mainly applicable to coal

on August 30, Shijiazhuang Coal Mining Machinery Co., Ltd. obtained a national patent for the main part of the first domestic coalbed methane drill locomotive product developed by Shijiazhuang Coal Mining Machinery Co., Ltd. since (2) the process technology of the auto parts manufacturing enterprise is backward

coalbed methane drilling locomotive is a product developed by the stone coal machinery company in 2009 to fill the domestic gap. It is mainly applicable to the construction of surface gas extraction wells and mine emergency drilling in coal mining areas, as well as the construction of shallow oil and hydrological wells

in the process of developing coalbed methane drill locomotive products, the designers of the stone coal machinery company designed the conventional integral non retractable derrick as a retractable mast type in order to facilitate the overall loading of the derrick and the transportation of vehicles. The telescopic mast mast has a telescopic stroke of 7.5 meters. In the retracted state, the total length of the mast is 13.5 meters, which is convenient for the road driving of the drilling rig truck; In the fully extended state, the total length of the mast can reach 21 meters, but in the actual use, the casing with a length of less than 15 meters can be easily used, and the maximum drilling depth can reach 1500 meters
