Measurement while drilling (MWD) is the key for underground directional drilling in coalmine. In this paper, an uphole monitor for MWD is developed to process and display downhole measure data. Firstly, an explosion-proof computer is developed, which can be used in explosive gas atmosphere. The flameproof enclosure and intrinsic safe type of protection have been employed to meet the needs of explosion-proof and communication with measure unit. A Windows-based software is subsequently developed to show the measure result and generate the in-seam drilling trajectory. The uphole monitor has been integrated into directional drilling system and demonstrated by the application in China’s coalmines.
