Abstract：Analyzes the problems existing in underground coal mine cable MWD system, mainly involving the two aspects of drilling tools and process factors, in view of the status quo that the geological structure of coal mining getting more complex, put forward the coal mine mud pulse,electromagnetic wave, acoustic wave and electromagnetic coupling four kinds of wireless MWD systems,introduces the system composition, technical principle, summarizes the application of mud pulse MWD system, electromagnetic wave MWD system in various mining areas and the ground test results of acoustic MWD system andelectromagnetic induction coupled transmission MWD system, also summarizes the shortcomings of the four kinds of wireless MWD systems combined with the field application and test results. Also introduces the research status, technical principle of continuous wave MWD system and the necessity of developing continuous wave MWD system in underground coal mine.Finally, the characteristics and optimization direction of the wireless MWD systems are pointed out, and according to the new requirements of coal mine safety development under the new situation, the development of wireless MWD system in underground coal mine is proposed, which provides reference for the optimization and improvement of wireless MWD technology and equipment in underground coal mine.
