| Abstract: | Straight guided drilling technology is introduced in underground coal mine. According to the rock formation property and drilling equipment of the coal mine, using the assembly drilling tools which are developed and optimized, through the drilling experiment, the hole quality and the hole success rate is greatly improved, the problem of borehole deviation has been solved better. |
