“…Therefore, coal mine methane drainage and utilization promotes mining safety, recovers methane resources, and reduces GHG emissions (Chen and Cheng 2015;Bibler et al 1998;ECE 2010;ESMAP 2007;Karacan et al 2011;Keim et al 2011;Tu and Chen 2002). Globally, CMM drainage and usage is attracting increasing attention in major coal-producing countries, such as the USA, Australia, and China (Bibler et al 1998;Kirchgessner et al 2002;Wang et al 2012;Yang 2009). …”

Quality and quantity of pre-drainage methane and responding strategies in Chinese outburst coal mines

Coal and gas outburst and gas explosion are most important coal mine disasters throughout the world. Predrainage is widely accepted and performed to prevent and control methane-related disasters in Chinese outburst mines. Boreholes for pre-drainage are drilled directly into the outburst-prone seams and are theoretically able to capture most of the seam gas that has a high concentration of CH 4 . The methane drainage practice in the Huaibei coalfield suggests that high-outburst mines achieved better efficient during pre-drainage and better effects in methane use than the other outburst mines. This implies that pre-drainage was primarily implemented to eliminate the outburst hazards of outburstprone seams and not to recover methane resource and reduce methane emissions in China. This idea resulted in a greater emphasis on the quantity rather than the quality of predrainage methane, and even the quantity of pre-drainage methane itself was not sufficient in eliminating outburst hazards. This idea and related policies on methane drainage should be transformed urgently. Methane pre-drainage can be greatly improved by making full use of those unavoidable intense boreholes. It is suggested that operating a highefficiency drainage system and developing or popularizing high-efficiency techniques, materials, and equipment for borehole sealing can improve the quality of pre-drainage methane. Simultaneously, extending the pre-drainage time by cooperating with artificial channels can produce the fullest potential of intense boreholes and maximize the quantity of pre-drainage methane. These efforts would benefit the overall mine safety, mine productivity, and methane resource exploitation and usage, as well as the environmental impact, particularly with regard to greenhouse gas emissions.

“…However, most economic evaluations currently target CBM reserves at or above a proven level (Kirchgessner et al 2002;Robertson 2009;Zhang et al 2004;Wang et al 2004). A few scholars (Mu and Zhao 1996), who studied economic evaluation methods for the exploration phase, have recommended the use of adjusted conventional natural gas evaluation parameters to perform economic evaluations in resource-rich areas that have been explored only at a low level.…”

Because forecasting a development program during the target selection phase of exploration for coalbed methane (CBM) is impossible, the conventional method that relies on a conceptual (or detailed) development program cannot be used during the economic evaluation of CBM resources. Hence, this study focuses on establishing an economic evaluation model based on the characteristics of the target selection phase. The discounted cashflow method is applied to the construction of the model with the assumption that there is a uniform distribution of production wells. The computational error generated by the assumption is corrected by introducing a correction factor based on the production profile of single CBM wells. The case study demonstrates that the blocks lacking economic value can be screened out, and the most advantageous targets can be found by computing the resource values in the best-and worst-case scenarios. This technique can help to reduce wasted investments and improve the quality of decision-making in selecting targets for exploration.
