“…As a result, carbon currently contributes approximately 63% of the gaseous radiative force contributing to climate change. Atmospheric carbon had increased to 390.5 ppm by 2011, according to the IPCC reports [3][4][5], thus exceeding pre-industrial levels by approximately 40% [6]. China has surpassed the United States as the world's biggest carbon emitter.…”

China has overtaken the United States as the world's largest producer of carbon dioxide, with industrial carbon emissions (ICE) accounting for approximately 65% of the country's total emissions. Understanding the ICE decoupling patterns and factors influencing the decoupling status is a prerequisite for balancing economic growth and carbon emissions. This paper provides an overview of ICE based on decoupling elasticity and the Tapio decoupling model. Furthermore, the study identifies the factors contributing to ICE changes in China, using the Kaya identity and Log Mean Divisia Index (LMDI) techniques. Based on the effects and contributions of ICE, we close with a number of recommendations. The results revealed a significant upward trend of ICE during the study period 1994 to 2013, with a total amount of 11,147 million tons. Analyzing the decoupling relationship indicates that "weak decoupling" and "expansive decoupling" were the main states during the study period. The decomposition analysis showed that per capita wealth associated with industrial outputs and energy intensity are the main driving force of ICE, while energy intensity of industrial output and energy structure are major determinants for ICE reduction. The largest contributing cumulative effect to ICE is per capita wealth, at 1.23 in 2013. This factor is followed by energy intensity, with a contributing cumulative effect of −0.32. The cumulative effects of energy structure and population are relatively small, at 0.01 and 0.08, respectively.

“…As shown in Figure 1, gas accidents accounted for 10.4% of the total number of accidents in coal mines in China during 2006-2015, while gas accidents accounted for 27.9% of the total number of deaths [4]. For these reasons, improving the efficiency of CBM development is very important for optimizing the mix of energy resource used in China, for improving coal mine safety, and additionally for protecting China's atmosphere [5][6][7][8][9]. Coalbed methane development in China can be divided into two classes: surface CBM development and underground gas extraction.…”

“…This is three or four orders of magnitude lower than in the United States, Australia, and other developed countries. Therefore, increasing seam permeability is probably the most promising technology to promote CBM development in China [8,[13][14][15]. Coalbed methane development in China can be divided into two classes: surface CBM development and underground gas extraction.…”

Abstract:Coalbed methane (gas) is a high quality and clean resource, but it also causes disasters in coal mines in China. The low permeability of coal seams is the main reason that developing coalbed methane (CBM) as an energy resource is difficult, so increasing coal seam permeability is the key to CBM development in China. In this paper, the principal techniques for seam permeability enhancement are presented. The paper focuses on hydraulic technology for seam permeability enhancement (HTSPE), which is considered an economic and highly efficient technology for seam permeability enhancement. The process of HTSPE development is reviewed and the current status of the theories behind HTSPE and the technology and equipment for its use are summarized. The goal is to identify the gaps in HTSPE research and the problems in its implementation. In the future, integration and diversification of the technologies along with on-board intelligence and miniaturization may be the trends for the equipment. Finally, it is shown that tree-shaped borehole fracturing can be used to develop CBM in underground coal mines. This study could be used as a valuable example for other coal deposits being mined under similar geological conditions.
