60m 670mm Blindhole Raise Boring Drill Similar with Easer L for Drill Opening Holes
Introduction The purpose of blindhole is to provide a free surface and a free space for large mining. Upward excavation directly affects the continuity and balance of underground mine production. At present, manual excavation is widely used in blindhole construction, while traditional raise boring rigs are used in a few mines, their safety, efficiency, environmental protection and other aspects can not meet the requirements of modern large and medium-sized mines. CY-R40C blindhole raise boring machine is the first one in China, which is especially used in the excavation of various opening holes. And when it adopts the boxhole drilling methods, its diameter can reach 670mm, and the depth can reach 60m. CY-R40C blindhole raise drill has the advantages of fast rotary installation, safe and efficient operation. In addition, the blindhole RBM can propel itself without the concrete platform. The technical indexes of the blindhole raise boring drilling rig are in the leading international level, which can fully meet the construction requirements of blindholes in various types of underground mines.
Thanks to its compact design, the CY-R40C boxhole raise boring rig can be used in gold, copper and other underground mines under space constraints.
CY-R40C versatile boxhole raise boring rig can be used for drilling opening holes in block cave, sub level caving and sub level stoping mine. And it can also be used for precondition holes, paste fill tube holes, media holes, slot holes, back filling, drainage holes, ventilation holes, filling holes, cable holes, through passes and tunnels, and narrow vein mining applications.
1, Automatical rod loader
Our boxhole raise boring machine adopts automatic positioning technology and dynamic plug-in structure, the boxhole drilling rig can realize fully mechanized connection and unloading rod operation without any other person's command through two hydraulic wrenches.
2, Our patented technology and high-level configuration Our boxhole raise boring machine use our own patented technology as well as the well-known brands of electrical devices, hydraulic components and transmission parts in the world.
3, Two drilling modes and three operation modes The control system of our boxhole raise boring machine supports two drilling modes(high accuracy drilling mode and fast speed drilling mode) and three operation modes(manual operation, wireless operation and wired operation).
4, Self-Lubricating and maintenance-free crawler chassis The customized hydraulic crawler chassis can achieve automatic shift of two gears, wireless driving on and off the vehicle and higher efficiency.
5, Automatic pressure-maintaining steady machine system Automatic pressure-maintaining steady machine system make the boxhole raise boring drill can be put into use immediately after arriving at the working station, and can leave immediately after finishing the work, saving a lot of time for concrete pouring, installation and disassembly.
6, Diesel-electric dual power hydraulic system As for our boxhole raise drilling rig, the electric power is responsible for all the functions of field operation, while diesel power is responsible for walking function.
7, RCS Intelligent control system The boxhole RBM installs RCS intelligent control system with safety protection, automatic operation, fault diagnosis, data storage, internet communications, digital display and other functions.
1, Longhole drilling
The blindhole raise boring machine can drill holes with diameters from Φ220mm and depths of 200m.
2, Boxhole drilling
Our blindhole raise drill uses tricone bit and reamer to drill the shaft simultaneously. It can drill a shaft with a diameter of Φ670mm and a depth of 60m.
3, Down Reaming
Our boxhole raise boring rig first drill the pilot hole with the tricone bit, remove the drill bit and the drill pipe, and install the reaming cutter head for the forward reaming operation from top to bottom. It can drill the hole with diameter of 670mm and depth of 200m.
4, Down Raising
First, the tricone bit is used to drill the pilot hole, and after the drill bit is removed, the reaming cutter head is replaced to perform the reamer operation from bottom to top.This process can drill a blind with a diameter of Φ1400mm and a depth of 200m.
