    Abstract:

    Based on the requirements of green geiological exploration, this article mainly introduces the drilling technical characteristics and application advantages of portable modular drill. The application effect of the drill is analyzed based on 30 drilling holes in different kinds of geological conditions. The drilling technical methods are explored integrating the portable modular rig, the efficient rock crushed thin wall bit and the green drilling fluid, as a result improving the drilling quality and efficiency, reducing the adverse impact of the engineering activities on the natural environment, obtaining a better social and economic benefits. At the same time, the environmental protection and treatment measures in engineering activities are explored, and the management issues of green exploration work is discussed. At last, some suggestions are put forward for the wide application of drilling rig in the future, which provide a better guiding significance for the continuous promotion of green geological exploration work.
