Abstract: Aiming at the problem of large workload, long cycle and high cost of the existence of water drainage face dedicated drainage tunnel roadway and high gas,high dust,roadway excavation project,the author study the use of screw motor combined with MWD technology and back to the drag casing(sieve) pipe technology in the construction of short-distance roadway precision drilling,through the drilling optimization design, accurately drilling trajectory control and other methods,the paper summed up a set of coal mine underground tunnel in the short distance precision drilling and casing technology.The application results in Huaibei Mining Area show that, 200 m within the precision drilling can smooth hit the target(within the range of 3.6 m×3.0 m), it can effectively replace the drainage roadway with the danger of water inrush, it can solve the problem of dust explosion and explosion in high coal(rock) dust roadway excavation.It can eliminate the security risks in the coal mine production process, improve the production efficiency and reduce the cost.
