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 hard rock. The system is thought to have been invented independently by Stenuick. Origin of the nameDTH 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 mechanis. .
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 flui.

If you have an experienced heavy hauler on your team, you already understand the amount of planning and work that goes into transporting heavy construction equipment. Many times your construction equipment supplier will be able to give you guidance on selecting a professional transportation company. .
There are a number of variables you will encounter when you begin to develop your transportation plan. Depending on the regional climate and. .
As your transportation plan starts to come together, everyone’s roles and responsibilities need to be clearly defined to ensure smooth transit. A spotter can help ensure the equipment is loaded in the correct position as the driver will likely not have a clear line of. .
When the equipment is being loaded on the trailer’s deck, its center of gravity will shift. This process should be done slowly as the driver needs. .
All transportation equipment should be clean, well maintained, and free of dirt, debris, or oil to create a secure platform for construction equipment. These elements can reduce traction and make the loading and unloading challenging. Work with your.

Core drilling is an important process for any project that requires gauging the properties of different materials. In some cases, teams may prefer using techniques such as mud rotary drilling. The downside to this, however, is that it doesn’t get as accurate as a sample as core drilling, as the mud rotary drilling. .
The basic concept of core drilling is using a hollow bit to extract a sample from a certain surface. There are two types of core drilling, and each of these processes works in a slightly different way. .
There are some risks to core drilling that organizations will have to accept, especially when weighed against the benefits of core drilling. This is why it’s important to have a solid set of safety practices to alleviate the risks associated with core drilling.. .
The risks workers face when core drilling can vary depending on the type of material being extracted, the location, the equipment used, and. .
There are different types of core drilling equipment to be used depending on the specific application. Here are some of the most common types of core drilling machines: 1..
