 · ROTARY BLAST HOLE DRILL The D90KS is a diesel powered, selfpropelled crawler mounted blasthole drill for mining. It is equipped to rotary drill 229 to 349 mm (9" to 13 3/4") diameter holes. This modern design, with excellent visibility, powerful slewing, and strutless mast support, results in high mobility, good hole spotting, and maximum productive time. The D90KS is one .

rock drill works concurrently to widen the subgrade and drill rock for ditch excavation. Blasting methods typically involve some form of controlled blasting in which individual boreholes or rows of holes are initiated in a sequence that controls rock movement and achieves a finer fragmentation. The purpose of controlled blasting is

Some examples of advancements in drilling technology are presented below: Horizontal Drilling. Horizontal drilling is a directional drilling process aimed to target oil or gas reservoir intersecting it at the "entry point" with a nearhorizontal inclination, and remaining within the reservoir until the desired bottom hole loion is reached. While the construction of a directional well ...

 · In order to improve performance, the drilling and blasting industry is rapidly adopting technology in all forms. In the modem mines it is very common to encounter the latest forms of laser measurement technologies, global positioning systems (GPS), communiion technology and computer systems. The developments in the areas of planning and design of blasts, drill monitoring, .

 · "The technology incorporates sensors, machinelearning algorithms and drilling technology in a twopass system. "In the first pass, we drill down the dip of the orebody using a diamond drill to create a pilot hole halfway between the hanging wall and footwall of an ore vein and we guide the drill bit using our near borehole imaging tool (NBIT). Then, in the second pass, we use a .

This rig can be fitted for both downthehole (DTH) drilling and rotary drilling and has a CANBuscontrolled hydraulic system for higher availability. D90KS Rotary blasthole drill rig. Our D90KS blasthole drill is ideal for high altitudes as well as harsh desert and arctic conditions. It drills holes with a diameter of 229 349 millimeters (9 13 ¾ inches) down to a maximum single ...

Drilling and blasting technology is one of the main methods for pressure relief in deep mining. The traditional method for blasting hole blockage with clay stemming has many problems, which include a large volume of transportation, excess loading time, and high labor intensity. An environmentally friendly blast hole plug was designed and developed.
