A drifter drill, sometimes called a rock drill, is a tool used in mining and civil engineering to drill into rock. Rock drills are used for making holes for placing dynamite or other explosives in rock blasting, and holes for plug and feather quarrying. While a rock drill may be as simple as a specialized form of chisel, it may also take the form of a powered machine. The mechanism may be worke. History and typesThe simplest form of rock drill consists of a long chisel or drill steel that was struck with a . , who worked unsuccessfully as a silver miner in the early 1860s before taking up journalism, described t. .
In reciprocating power drills, the drilling cylinder is mounted on a feed-screw, such that as the hole is drilled and the drilling point recedes from the rock face, the drill-bit continues to move into it, while the anchor point (on th. [pdf]

Excavators are also called diggers, scoopers, mechanical shovels, or 360-degree excavators (sometimes abbreviated simply to "360"). Tracked excavators are sometimes called "trackhoes" by analogy to the backhoe. In the UK, wheeled excavators are sometimes known as "rubber ducks". OverviewExcavators are primarily consisting of a , dipper (or stick), , and cab on a rotating platform known as the "house". The modern excavator's house sits atop an undercarria. .
Modern hydraulic excavators come in a wide variety of sizes. The smaller ones are called mini or . For example, smallest mini-excavator weighs 2,060 pounds (930 kg) and has 13. [pdf]
During casing running, plot the casing weight and pit levels on the graph (described earlier) and compare them with the theoretical values previously plotted to detect any possible abnormal conditions. .
Before starting casing, the drilling supervisor should hold a pre-job safety meeting and confirm the following with the crew: 1. Remove unnecessary tools. 2. Good Housekeeping before the job 3. Rig up Casing handling equipment: Using appropriate hand. .
A circulation sub, fitting the casing thread, equipped with a WECO connection, shall be readily available on the rig floor at all times during casing running. [pdf]

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 fluid (air, water or ). The DTH hammer is one of the fastest ways to drill hard rock. The system is thought to have been invented independently by Stenuic. [pdf]
