Key Technology of Full Section Crawler Drilling Rig in Thin Coal Seam

To solve the problem of thin coal seam gas extraction and promote the application of advanced gas extraction equipment in thin coal seam mining area, the drilling machine suitable for the low section of thin coal seam in low roadway was studied. This paper mainly studies the overall structure layout and key technology of the drill, and introduces in detail the design of the integrated low crawler body and the low function of the drill with the built-in low crawler body of the tilting angle adjusting and stabilizing device. At the same time, the control system of the drilling rig including the mobile main control board and the functional switch valve is studied. The crawler drilling rig for the construction of low full-section thin coal seam is developed. The good adaptability of the drilling rig in the construction of low roadway drilling and the high efficiency for the construction of thin coal seam drilling are further verified through the field application.
