Methane is an explosive gas in the range of 5 per cent to 15 per cent methane in air. The application of best practices for methane drainage and use is critical to reduce methane-related accidents and explosions that all too often accompany coal mining, while also contributing to environmental protection through reduction of greenhouse gas (GHG.

The application of best practices for methane drainage and use is critical to reduce methane-related accidents and explosions that all too often accompany coal mining, while also contributing to environmental protection through reduction of greenhouse gas (GHG) emissions.

Coalbed methane (CBM) drainage in underground coal mining is of significance to guarantee mining process safety and bring valuable environmental benefits, as the drainage could help to eliminate methane-related accidents, reduce greenhouse gas (GHG) emissions and Cited by:   Coalbed methane is generated in the coalification process.

The two main sources of methane are biogenic and thermogenic, as shown in Fig. 1 (Moore, ).Normally, the thermogenically derived methane content in coal is higher than the content of biogenic methane (typically less than 6 m 3 /t).

In a specific basin, the biogenic methane is more likely to occur in the shallow coal beds, whereas Cited by:   Evaluation of methane drainage and use effectiveness. The practice of methane drainage and utilization has promoted enhanced safety, environmental mitigation and energy recovery Drainage and use of methane from coal-fields book the Luling mine.

Pre-drainage eliminates the risk of outbursts in the Nos. 8, 9 and 10 seams, and post-drainage reduces the overall gas emissions from coal by: Based on our analysis, several improvements, such as protective seam mining, drainage system upgrades and the use of medium-quality methane by local industry, are directed.

same methane content and no drainage system. Using that comparison, the usage of a drainage system shows an increased NPV of million dollars at a 0% inflation rate, million dollars at a 5% inflation rate, and million dollars at a 10% inflation rate. Thus, the use of a drainage.

Combined with the coalbed methane field operation, the well is conducive to carbon dioxide huff and puff, the optimized production strategy is: water drainage in the early period, and carbon dioxide huff and puff at middle-late stages of development.

Methane Capture and Use. You've probably heard about the three R's. While it's important to reduce, reuse, and recycle as much as you can, it's hard to avoid throwing out some trash every week. Trash that cannot be recycled or reused often ends up in landfills, where it produces methane as it decomposes.

Methane is a very powerful greenhouse gas. The methane is then conveyed to the surface through piping within the mine. In Europe, methane recovered by gas drainage systems is more commonly used as an energy source than in the U.S., where much of the gas is vented into the atmosphere.

There is little published data on methane emissions from gas drainage systems. Information Circular Handbook for Methane Control in Mining. By Fred N. Kissell, Ph.D. DEPARTMENT OF HEALTH AND HUMAN SERVICES.

Get this from a library. Best practice guidance for effective methane drainage and use in coal mines. [United Nations. Economic Commission for Europe,;] -- Today coal supplies around 30 per cent of global primary energy and 40 per cent of global electricity.

Coal extraction has become increasingly challenging as shallow reserves are exhausted and deeper. Get this from a library. Best practice guidance for effective methane drainage and use in coal mines.

[United Nations. Economic Commission for Europe.; Methane to Markets Partnership.;] -- Coal mines are not only a safety management challenge but also a major source of greenhouse gas emissions. Methane release during coal mining creates unsafe working conditions in underground coal.

Drainage of methane in advance of mining is inherently a safe method for controlling methane emissions during mining and contributes to efficient use of mining equipment. The Bureau of Mines has demonstrated that drainage of methane through horizontal holes drilled from a shaft bottom is a successful method of.

Storing and Using CO2 for Enhanced Coalbed Methane Recovery in Unmineable Coal Beds of the Northern Appalachian Basin and Parts of the Central Appalachian Basin by Stephen F. Greb1, Cortland F. Eble1, Ernie R. Slucher2, Kristin M. Carter3, Katharine Lee Avary4 1 Kentucky Geological Survey, University of Kentucky, Lexington, KY In a coalbed methane (CBM) well, pumping water from the coalbeds lowers this pressure, facilitating the release of methane from the coal for extraction and use as an energy source.

Water pumped from coalbeds during this process--CBM 'produced water'--is managed through some combination of treatment, disposal, storage, or use, subject to.

The amount of methane that is captured through methane drainage systems. Methane used: The amount of captured methane put to productive use (e.g., natural gas pipeline injection, fuel for power generation, etc.). Tailgate: An access tunnel to the longwall.

A theoretical qualitative analysis was performed in regards to the spontaneous combustion hazards. The software FLUENT was employed to investigate the theoretical mathematic model. The methane drainage can increase the range of easily spontaneous combustible region.

The oxidation zone width increases with increasing drainage pressure near the hole. Coal Bed Methane: From Prospect to Pipeline is the proceedings of the 25th anniversary of the North American Coal Bed Methane Forum.

It provides the latest advancements in the production of coal bed methane covering a variety of topics, from exploration to gas processing, for commercial utilization.

Additionally, it presents the origin of gas in coal, reservoir engineering, control of methane. With regard to underground mining, methane is a gas that, on the one hand, poses a threat to the exploitation process and, on the other hand, creates an opportunity for economic development.

As a result of coal exploitation, large amounts of coal enter the natural environment mainly through ventilation systems. Since methane is a greenhouse gas, its emission has a significant impact on global.

desorption of methane from the coal (fi g. Over time, volumes of pumped water typically decrease and the production of gas increases as coal beds near the well bore are dewatered. The need to decrease CO 2 emissions favors the increased use of natural gas as an alternative to coal.
