Numerical Simulation Study on Coal Bed Methane Development
In order to find out the advantages and disadvantages of various development methods of coal bed gas, the experimental block provided by the field is studied, the component calculation model is established by CMG numerical simulation software on the basis of fine geologic modeling. Four development schemes are designed which are depleted development, development of hydraulic fracturing, develop...
متن کاملDetermination and assessment of coal bed methane potential using rock engineering systems
The presence of methane in coal mines is one of the major problems in underground coal mines. Every year, in underground coal mines, a lot of casualties due to outbursts and explosions of methane gas is occurring. Existence of this gas in the mines not only creates a difficult and dangerous situation for work but also makes it more expensive. The release of this gas to the air causes a further ...
متن کاملEquilibrium Strategy Based Recycling Facility Site Selection towards Mitigating Coal Gangue Contamination
Environmental pollution caused by coal gangue has been a significant challenge for sustainable development; thus, many coal gangue reduction approaches have been proposed in recent years. In particular, coal gangue facility (CGF) construction has been considered as an efficient method for the control and recycling of coal gangue. Meanwhile, the identification and selection of suitable CGF sites...
متن کاملEstimation of coal seams gas content for evaluating potential use of methane drainage system in Tabas coal mine
Methane gas emission, accumulation, and explosion are the most important risk factors in underground coal mines. Hence, having a knowledge of methane gas emission potential in underground coal mines is of crucial importance in preventing the explosion risk, loss of life, and property, and providing miners' safety. The purpose of this work is to provide the prediction maps for the C1, C2, and B2...
متن کاملVibration signal analysis of coal-gangue based on Hilbert marginal spectrum in clean coal technology
With the increase of social demand on environmental quality, the clean coal technology (CCT) is one of the most effective measures for environmental control. It is an important means in CCT to decrease the gangue content. Targeting at distinguishing the top-coal and gangue, this paper discussed coalgangue interface detection on fully mechanised mining face. The Hilbert marginal spectrum based o...
