In 2018, the performance of the coal sector in China improved, which was attributed to a number of factors, such as favourable domestic economic conditions, the ongoing supply-side reform and coal industry consolidation. In addition, there was high market demand from the steel sector, increased power consumption and a recovery in thermal power generation. These market conditions stimulated growth in coal prices, which although hiked to USD 120 per tonne on international markets in July 2018, remained at healthy levels. The stronger performance of China’s coal sector in 2018 was also a result of improved balance between supply and demand, supported by implementation of the government’s regulatory measures on coal pricing and import volumes throughout 2018. The production efficiency and profitability in the sector increased. The revenue of the major coal mining enterprises rose by 5.5% y/y to RMB 2.3tn, according to China National Coal Association, while their profit increased by 5.2% y/y to RMB 288.8bn. The number of coal mining enterprises rose to 4,505, up from 4,435 in 2017, while the number of coal mines was cut to 3,373, down from 3,907 in 2017. The average annual production capacity expanded to about 920,000 tonnes.

The coal mining industry in China has been undergoing an intense consolidation process, which has resulted in a decreasing number of small inefficient businesses and a growing number of large coal enterprises. Due to their extensive scale of operations and big market shares, SOEs are the sector’s main revenue generators. In 2018, the country’s top ten coal producers generated over 34.6% of the total revenue of coal mining, up from the 27.1% share in 2017. The government’s industry reforms envisage further consolidation of the mining sector, which is likely to intensify the M&A activity. In order to boost their profits along the value chain, coal producers are expected to further expand their presence into segments such as syngas, olefins and liquid fuels, as well as coal-to-oil conversion. They will also work on diversifying their business scope with renewable energy development, power generation and transportation.

由于内蒙古根据各企业超产情况发放煤管票，导致之前超产的地方煤矿产量释放受限。8 月当月，全国煤炭产量 31602万吨，同比增长 5.0%。部分区域在台风过后出现高温，刺激了电煤需求小幅回升，加之来水较往年偏枯一成，也支撑电煤需求有所反弹，8 月全国煤炭销量为 30500 吨，同比增长 6.6%。动力煤价格相对平稳。

基于煤炭开采现状分析，系统梳理了煤炭安全绿色开发相关政策内容，从行政管制和经济工具角度对现有政策进行分类，通过构建煤炭安全绿色开发政策评价指标体系，对相关政策进行评价，分析煤炭开采政策存在的问题。最后，提出相应的政策建议。

我国煤炭企业在转型发展过程中，由于煤炭产品的同质性及煤炭市场的不确定性，使煤炭企业面临严峻挑战，在这种情况下，市场营销起着至关重要的作用。本文在分析转型期煤炭企业市场营销现状的基础上，对煤炭企业转型过程中市场营销存在的问题提出一系列营销策略。

分析了神华准能集团（以下简称准能集团）数字矿山的功能需求，设计了准能集团数字矿山系统架构、逻辑框架和物理框架，对准能集团数字矿山数据标准化进行了研究，并设计了主数据管理总体功能架构和数据系统集成总体架构，最后对准能集团数字矿山建设进展进行了阐述。

近几年，山西煤炭市场在持续低迷的同时受到国家供给侧大力改革及煤炭行业去产能政策的影响，经营陷入困境。其中，在全面成本的控制方面需要制定良好的管理策略，帮助煤炭企业在预控方式上掌握主动权。党的十九大报告明确提出“建立全面规范、透明、标准、科学、约束有力的预算制度，全面实施绩效管理”，这就意味着全面预算管理在我国将步入快速发展的新阶段。随着企业的快速发展，业务更加复杂，信息传递受到阻碍，传统的全面预算管理已经无法实现其自身的战略管理价值，利用信息技术手段优化全面预算管理体系势在必行。

鄂尔多斯市纳林河矿区为国家新批复的亿吨级矿区，是我国未来重要的煤炭供给地之一。本文重点分析了纳林河矿区煤炭开发在生态环境保护、与天然气开采重叠、深井开采、井下涌水量大等方面存在的问题，探讨相应的对策，为矿区下一步科学合理开发提供参考。
