Coal price may vary significantly within a given coal seam, and the accurate characterization of coal price plays an important role in the rational development and utilization of coal resources. A geostatistics-block-based method is proposed to obtain the spatial correlation of borehole survey data and map the heterogenous distribution of coal seam thickness and coal quality (including calorific value, volatile content, ash content, and sulfur content). A block model of thermal coal price is next established considering the spatial distribution of coal quality parameters. Taking an undisclosed coal mine as an example, the estimation process of coal price block model is described in detail, and the mining sequence among several panels is optimized considering the heterogenous coal price. The coal price ranges from 814 to 1671 Chinese Yuan/t within the research area, and the net present value is increased by 1.53% after the optimization of the mining sequence. The result indicated that the coal price is generally heterogenous in a coal seam, and it has a significant influence on the mining sequence. The accurate modeling of coal seam properties has wide applications in mining engineering.

Article Synopsis
- The study examines various pathways for transitioning coal power that can achieve the same carbon emission reduction targets, focusing on costs associated with different mitigation technologies.
- By using a dynamic optimization model for over 4,200 coal plants in China, the research finds that plants can retrofit multiple technologies, retiring at lower costs while enhancing grid stability.
- Optimizing these transition pathways could save China over $700 billion or increase emissions reductions substantially without extra expenses, aiding in a cost-effective phase-out of coal and supporting carbon neutrality goals.

Mitigating methane (CH) emissions from China's coal mines as the largest contributor to anthropogenic CH emissions is vital for limiting global warming. However, the knowledge about CH mitigation potentials and economic costs of Chinese coal mines remain poorly understood, which hinders the formulation of tailored CH mitigation strategies. Here, we estimate and project China's provincial coal mine methane (CMM) emissions, mitigation potentials and costs under various coal production scenarios, by integrating the dynamic emission factors of CMM and key abatement technologies.

Both the global and European energy sectors have been undergoing a deep transition for several years, associated with a reduction in the overall share of conventional coal-based energy in favor of new technologies, especially energy from renewable sources (RES). This transition is moving from centralized production towards distributed technologies and from providing only energy to end users towards combining innovative products and services with it. Electricity consumers are becoming prosumers connected to the grid and generating an increasing amount of energy.

As an important strategic energy base in China, Inner Mongolia's energy exports are dominated by coal and electricity. Under the background of "double carbon" target, the energy transition of Inner Mongolia is of great significance to China's energy security and carbon emission reduction. Based on the energy policy simulation model (EPS model), this paper explores the path of energy transition in Inner Mongolia by constructing the scenarios of developing renewable energy, developing CCS technology and carbon pricing, and simulating the policy situation based on the reality of Inner Mongolia and the energy transition experience of developed countries and regions.

The recycling of used lead-acid batteries is currently the main source of lead in the world. More than 50% of the weight of a used lead-acid battery is battery paste, in which lead occurs in compounds with oxygen and sulfur. In pyrometallurgical processes of battery paste, coke or coke breeze is used as a traditional additive acting as a fuel/reducer.
