Compared with YT29A, the speed is faster and diamond drills rock. YT29S/S82air-leg rock drill is a heavy-duty air-leg rock drill with high efficiency and low consumption characteristics. It is especially suitable for use in the construction of railways, highways, hydropower, etc., and is also used. .
S82air-leg rock drill is a heavy-duty air-leg rock drill with the characteristics of high efficiency and low consumption. It is especially suitable for use in the construction of railways, highways, hydro power, etc., and is also used for mine tunneling and various rock drilling operations in.
[pdf] 1. Prepare the rock-drilling cavern, the specifications of which can be determined according to the method of drilling. Generally speaking, the height of the cavity is 2.6-2.8 meters when drilling a horizontal hole with a down-the-hole drill. When drilling upward, downward, or inclined holes, the width of the cavity is. .
1. When starting to work, carefully check whether the gas and water pipelines are firmly connected. Check for air leaks and water leaks. 2. Check whether the lubricator has been. .
When opening the hole, start the motor first, and pull the push handle of the manipulator after the transfer is normal. Make it get proper.

DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanism followed the bit down into the hole. Applications were later found for the DTH method. .
A down-the-hole drill, usually called DTH by most professionals, is basically a screwed on the bottom of a . The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a. .
A is first thought to have been used for rock drilling in 1844. Many quarries used hand held tools that required the driller to suspend himself from a rope over the. .
In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the fluid (air, water or drilling mud) used to. .
DTH products can be used in the following applications:• Mining- drill and blast holes in open pit mining, where the drill operator will drill several holes, then. Down the Hole Hammer (DTH) is a versatile horizontal drilling method, capable of tunneling through the toughest soil types and rock formations. DTH can break through cobbles, boulders, and even solid rock — which allows our team to complete installations in otherwise impenetrable ground conditions.
