Patio drilling rig for underground mining

At present, the application of patio drilling rig has been quite popular, in many countries has replaced the traditional method of patio drilling and blasting. Compared with the general method of patio driving, the patio drilling rig has the advantages of construction safety, short well completion period, shortening the workload of horizontal roadway driving, smooth well wall and low noise. With the increasing perfection of large diameter and large torque patio drilling rigs of major brands, patio drilling technology is not only limited to underground mines, but also has been successfully used in horizontal drilling abroad. For example, a number of horizontal connecting tunnels between the two main tunnels in the English Channel were drilled with Rhino patio drilling rigs produced by Tamrock Company. The coal system uses drilling method to drill large coal bunkers and advance shafts for large-diameter shaft excavation. Ventilation shafts in railway tunnels and power station projects, underground warehouses drill transportation channels and shafts, etc. The use of low-rise drilling opportunities to reduce the cost of drilling rig working chamber excavation, and easy to assemble, handling, the world's underground mines (especially small and medium-sized mines) will increase the demand for such drilling rigs. With the progress of industry and the continuous innovation of technology, the scope of use of patio drilling rig is expanding, and it will certainly meet the higher requirements of people for its performance.
