Nearly Horizontal Hole Trajectory Is Controlled And Controlled Mechanism

With the spreading of the high-performance comprehensive mechanical mining coal technology in our country , for assure the security and high-yield of coal mine in our country, request not only improving the exploring precision, but also efficient discharging gas, and controlled directional drilling technology is of efficient way to resolve these question. It were fully analysis that the controlled factor and the non-controlled factor of the track of nearly horizontal hole in this paper, consider the controlled factor is mainly the using drilling tools and the drilling technical parameter, so emphasis and analysis these factor. Bring forward the mechanical model and the structural parameter of the assembly drilling tools by the stimulating trial, and validate the corresponding relation of the constructional way of the assembly tools and the track of drilling hole, searching the adaptive drilling technical parameter, and the screw drilling tool using in vertical drilling hole was used in the directional drilling of nearly horizontal drilling hole to test and research the drilling technical parameter; It was workout that the applied procure of calculating the coordinate of measuring point and simulating the track of drilling hole. It was born out that correctly applied the nearly horizontal directional drilling technology could improving the exploring precision of mining area, relieving the strain situation of unbalance proportion of the picking, discharging, mining, so it is important to the security and production of coal mine.
