| Abstract: | The coal mine gas is important factor affecting the coal mine production safety, at the same time as a new energy is increasingly important. Nearly horizontal directional drilling of CMM technology has been widely applied, in order to solve the security problems of coal mine gas and the development of new energy. The precise control of the drilling trajectory is the core of nearly horizontal directional drilling technology. This paper analyzes the factors that influence the directional drilling construction combined with drilling construction site, Summed up the experience and the law of the coal mine near horizontal directional drilling, and achieve the purpose of the precise control of the borehole trajectory. |
