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.

A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud). The DTH hammer is one of the fastest ways to drill. .
DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling. .
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.

The pump is responsible for compressing air. It may operate on a reciprocating mechanism (using pistons and cylinders) or a rotary mechanism (using screws or vanes). The pump draws in atmospheric air, compresses it, and sends it into the storage tank..
The pump is responsible for compressing air. It may operate on a reciprocating mechanism (using pistons and cylinders) or a rotary mechanism (using screws or vanes). The pump draws in atmospheric air, compresses it, and sends it into the storage tank..
The pump creates a pressure gradient (higher pressure at the outlet than at the inlet) to force air movement. A flexible diaphragm moves back and forth, changing the volume of an enclosed chamber. On the backstroke, the diaphragm pulls air into the chamber..
The working principle of this device relies on the conversion of electrical energy into mechanical energy. The electric motor present in the compressor provides power to the system, which drives the piston in a reciprocating manner..
This is achieved by using an electric motor, diesel, or gasoline engine to forcefully draw in ambient air and reduce its volume by compressing it, which increases the air’s pressure. Once compressed, the air is stored in a tank until needed.
