Apr 26, 2015· So, in order to remove coal from subsurface what we do is remove the overburden strata or the matrix present above coal. This process is called mining. Mostly Solids like Coal, Metals etc are retrieved from subsurface in case of mining. Drilling - Suppose Hydrocarbons are present in pore spaces of sandstone or limestone at subsurface.

Through this period, drill rig manufacturing companies started working with the coal industry to produce drill rigs suited to the drilling applications required and the environment. These rigs were generally more robust and configured for higher torque, lower rotational speeds for in-seam rotary drilling and directional drilling.
One inherent weakness in current UIS drilling practices is their inability to maintain the bit within the confines of the coal seam. As a result, coal seam boreholes tend to undulate, frequently drilling out of the seam. This requires pullbacks and branching, which duplicates drilling metres – and establishing a branch takes time.
Today, most of the global drilling rig fleet is owned by contract drilling companies. Typically, a term contract is entered into between the E&P operator and the contract driller. The rig services provided to E&P operators include experienced personnel and specialized equipment. Drilling contracts can be a mixture of types, depending on:

Borehole Mining No longer a science project, borehole mining is proving itself as a workable technology that can be applied to a number of industries. Hydraulically jet-cutting a cavern of rock 20 feet in diameter from a drilled bore hole allows this system to recover resources previously uneconomical for open pit or underground mining operations.
Coal began to be drilled. The basin currently contains approximately 30,000 producing wells, the majority of which are producing gas from the Fruitland Coal. ... Rig Equipment The drilling rig was a custom-built hybrid CT unit. At the time of the project, it was the only rig running in …

Drilling in the US' most prolific dry basins has continued to accelerate this year, despite an overall decline in gas-directed rig activity over the past several months. In the Marcellus Shale, rig count climbed by one this week to 68, reaching its highest level since mid-2015. In the neighboring Utica, the rig count was unchanged this week at 15.

In coal mining: Core drilling and rotary drilling. A second factor associated with a drilling program is the choice between core drilling and rotary drilling. In core drilling, a hollow drill bit is attached to a core barrel so that cylindrical samples of the strata can be obtained.
