“Hole-well-ground”integrated intelligent drilling system and key technologies

According to the direction requirements of a series of policies and standards on energy equipment manufacturing, coal mine robot and intelligent development policies and standards issued and released by the state, combined with the development trend of intelligent mining in the coal industry, the current situation of measurement and control of drilling electro-hydraulic parameters, drilling posture parameters, drilling geometry parameters, drilling geological parameters and working environment parameters in the process of drilling construction in China was studied.On the basis of this, according to the actual needs of operation, safety and decision-making control in the process of drilling construction, this paper put forward the definition and overall framework of intelligent drilling system construction of “hole-well-ground” integration of intelligent mining, introduced the detailed composition of the framework and node measurement parameters, and built the software and hardware platform of drilling data fusion based on geometric-geological-mechanical-environmental comprehensive perception.The key technologies and equipment that make up the intelligent drilling system were studied, including the measurement principle, composition framework and design scheme of borehole inclinometer technology, the principle, composition and design scheme of gamma parameter measurement, the composition and acquisition scheme of working condition parameters in the hole; the composition block diagram, transmission principle, excitation mode based on dipole antenna and mechanical structure of wireless electromagnetic wave transmission technology, and integration; the composition and implementation scheme of integrated drilling machine working condition parameter measurement of the drilling rig; the monitoring technology of the combination of the environmental sensing parameter measurement of the drilling field and network camera; the large screen electronic Kanban software system of the ground visualization based on the visual management technology.The result of technology realization shows that it is feasible to use the mature industrial ring network system of mine as the transmission medium combined with the collection, control, transmission and display means of various sensors to realize the “hole-well-ground ” integrated ground intelligent control drilling system in technology.It is technically feasible and can provide a reference for the improvement of the intelligent drilling measurement system and technical development.
