为了确保天井钻机在钻进导向孔时牙轮钻头处在岩石的有效体积破碎状态中工作,基于MATLAB软件,对大量深天井钻机钻进不同直径导向孔时的现场工作数据进行了分析和数据拟合,得出了天井钻机在最佳工作状态时的工作轴压、工作扭矩、钻进速度与牙轮钻头所在的掘进深度及普氏岩石硬度系数的数学模型,为设计先进的智能型大型深天井钻机全自动化导向孔钻进系统提供了理论依据。
In order to ensure that the rock drill works in the effective volume crushing of the rock while drilling the pilot hole, based on the MATLAB software, a lot of deep-well drilling rig drilling site diameter data when the pilot hole diameter analysis and data simulation The mathematic model of working shaft pressure, working torque, drilling speed and tunneling depth of roller cone bit and Platts’ rock hardness coefficient is obtained when the well drilling rig works in the best working condition. It is a good example for design of advanced intelligent large-scale deep The fully automatic pilot hole drilling system of the well drilling rig provides the theoretical basis.
