“…The Statistical Yearbook 2014 (NBSC 2016, Table 8.5) reports ensured reserves by region for 2013, which sum up to a total of 236290 Mt. To arrive at a number on recoverable reserves the figure is corrected by the average recovery factor of 48% obtained from Zhang et al (2016). Data on reserves in producing mines could not be obtained, as there seems to be no obligation to publish such information to the general public.…”

The achieved international consensus on the 1.5-2°C target entails that most of current fossil fuel reserves must remain unburned. Currently, a majority of climate policies aiming at this goal are directed towards the demand side. In the absence of a global carbon regime these polices are prone to carbon leakage and other adverse effects. Supply-side climate policies present an alternative and more direct approach to reduce the consumption of fossil fuels by addressing their production. Here, coal as both, the most abundant and the most emissionintensive fuel, plays a pivotal role. In this paper, I employ a numerical model of the international steam coal market (COALMOD-World) to examine two alternative supply-side policies: 1) a production subsidy reform introduced in major coal producing countries, in line with the G20 initiative to reduce global fossil fuel subsidies; 2) a globally implemented moratorium on new coal mines. The model is designed to replicate global patterns of coal supply, demand and international trade. It features endogenous investments in production and transportation capacities in a multi-period framework and allows for substitution between imports and domestic production of steam coal. Hence, short-run adjustments (e.g. import substitution effects) and long-run reactions (e.g. capacity expansions) of exporting and importing countries are endogenously determined. Results show that a subsidy removal, while associated with a small positive total welfare effect, only leads to an insignificant reduction of global emissions. By contrast, a mine moratorium induces a much more pronounced reduction in global coal consumption by effectively limiting coal availability and strongly increasing prices. Depending on the specification of reserves, the moratorium can achieve a coal consumption path consistent with the 1.5-2°C target.

“…This slowdown was in part due to the cost of coal extraction, which mirrors oil production costs suggesting that coal extraction for outer laying provinces whilst feasible was expensive to justify ( Fig. 1 E) [ 18 ]. This new policy change is reflected in the current five-year plan with a significant investment in renewables energy, as most of the cheap extractable coal in China has already been mined [ 19 ].…”

“…The fact that coal is considered as the primary energy source is unlikely to change for a long time according to China's national conditions. At present, two major problems exist in China's energy: First, with a large number of mines are becoming aged mines, China is now facing the problem of depletion of coal resources [2][3][4]. On the other hand, the demand of coal would increase in the future with the foreseeable growth of China's economy [5][6][7].…”

China faces the problem of depletion of its coal resources, and a large number of mines are becoming aged mines. Demand for coal, however, still increases due to the growth of China’s economy. Energy shortage might restrict the sustainability of China’s national economy. As one contribution to a solution, this paper proposes the innovative exploitation method of solid backfill coal mining (SBCM) technology to exploit parts of pillar-blocked (residual coal pillar resources under industrial square, RCPRIS) that protect industrial facilities. Thus, blocked coal resources may be converted into mineable reserves that improve the recovery ratio of mine resources. Also, waste would be removed from the surface reducing hazards of environmental pollution. Based on the case of the Baishan Coal Mine in Anhui, China, numerical simulation is used to study the size of shaft-protecting coal pillars (SPCP) required at different backfill ratios. Results show that the disturbance to a shaft caused by exploitation decreases with the increase of the backfill ratio. When using SBCM to exploit RCPRIS under the condition of 80% backfill ratio, compared with the caving method, a lot of pillar-blocked coal resources would be freed. The life of Baishan Coal Mine would be prolonged, resulting in appreciable social, environmental, and economic benefits.
