The invention relates to an orifice cooling and lubricating system and method for underground air directional drilling in coal mines. It is composed of a compressed air cooling device, a compressed air monitoring device and an active lubrication device. The wind monitoring device monitors the air supply parameters in real time during the directional drilling process, assists in judging the drilling conditions in the hole, feedbacks and controls the air pressure cooling device, and performs emergency treatment and noise reduction unloading to ensure construction safety in the hole; an active lubrication device is adopted , automatically add lubricating oil to the compressed air, reduce the abnormal wear of the directional drilling assembly in the hole, and improve the cooling effect of the directional drilling assembly in the hole; thus, the invention solves the problem of high-temperature gas cooling and hole Difficulties such as lubrication of internal directional drilling tool assembly and monitoring and handling of abnormal drilling conditions have reduced the probability of accidents such as fire in the hole, drill stuck in hole collapse, drill stuck in sediment, etc., improved drilling safety, and provided support for directional drilling construction technology and equipment support.
Description
technical field [0001] The invention relates to the technical field of tunnel drilling in underground coal mines, in particular to an orifice cooling and lubricating system and method for air directional drilling in underground coal mines. Background technique [0002] The occurrence conditions of coal seams in my country are complex, and broken and soft coal seams are widely distributed, especially with the gradual increase of coal mining depth and strength, the proportion of broken and soft coal seams is increasing. Gas is an important factor that plagues the safe and efficient production of broken soft coal seam mines, and gas drainage drilling construction is a key technical bottleneck restricting the efficient management of gas in broken soft coal seam mines. [0003] In recent years, in response to the problem of pore formation in broken and soft coal seams, my country has developed air composite directional drilling technology and equipment, that is, using the compres...
