The content of industrial components of coalbeds, one of the main parameters of coalbed methane (CBM) reservoirs, is crucial in the entire coal mine resource exploration and exploitation process. Currently, using geophysical logging data to determine the content of industrial components is the most widely implemented method. In this study, the PZ block in the Qinshui Basin was employed as a ...

Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the largescale exploitation of coal deposits. Since the mid20th century, coal has yielded its place to petroleum and natural ...

Exploration Geoscience/Prospecting. Searching for mineral deposits is the first step of the mining lifecycle. During this stage, large areas are often evaluated by airborne or groundbased surveys, such as those conducted by the BC Geological surveys provide important geological and geoscientific information about mineral and coal resources and potential.

Most coal exploration begins before any mining actually takes place. The most common method to accomplish this is by drilling coreholes. It is not uncommon for coreholes to be drilled just to obtain coal thickness and quality information describing moisture, sulfur, and ash contents, along with other useful information to determine the value ...

Indonesia's long history of coal exploration and commercial production began > 160 years ago, when the colonial era Bureau of Mines began the first coal exploration. However, the origin of the modern coal industry from the 1980s followed the introduction of two new investment and mining laws in 1967, which provided the framework for experienced foreign mining companies to enter.

Coal Geology. Coal is a combustible sedimentary rock formed from ancient vegetation which has been consolidated between other rock strata and transformed by the combined effects of microbial action, pressure and heat over a considerable time period. This process is commonly called 'coalification'. Coal occurs as layers or seams, ranging in ...

In the process of coal mining, prevention and control of water hazard is essential. It is the precondition for water hazard control to detect and determine the distribution of underground waterconducting channels. In urban environments, traditional methods such as active source seismic exploration and transient electromagnetic exploration commonly used in the field are difficult to carry out ...

Measurement while drilling is an important part of the intelligent development of coal mines. The main purpose of this paper is to comprehensively analyze the response characteristics of borehole drilling parameters and find a better method to predict rock mechanical properties based on drilling parameters. Firstly, six concrete blocks and multiple specimens were prepared with different ...

Mineral exploration is a complex process involving rigorous field work to collect data and conceptualization to fit the data into a plausible theory. Mineral exploration proceeds step by step taking into account aerial photographs, satellite imagery, geological maps, geophysical maps, and geochemical maps to delineate areas of interest.

In order to simulate the destruction of coal and the discharge process of coal chips in the drilling process, the birth and death element is used in the part where the coal model may contact with the drill bit. Under the bit pressure and rotation of the drill bit, the cutting teeth press into the coal and produce a cutting effect on the coal.
