Product description
The DTH drilling rig adopts an excellent motor, which has the
characteristics of high efficiency, convenient operation, low
investment and high economic benefit. Widely used in slope support,
quarry, water conservancy projects, anchor bolts, highway and
railway construction.
The principal drilling methods used in mines today are mechanical
ones in which a drill drives cutting tools into rock by means of
static or dynamic force. Percussion rock drills are the most
commonly used equipment for drilling in small-scale surface or
underground mining situations, whereas rotary crushing drills or
down the hole drills (DTHs) are generally employed for mining in
large-scale surface mines.
