通过复垦使采空土地恢复生产Returning Mined Land to Productivity Through Reclamation

本期《基石》即将付梓，世界各国领导人将在法国巴黎举行会议，就联合国气候变化框架公约下的第21次外空会议进行谈判。长期以来，这些会议的势头一直在增强，未来的基石问题将涵盖这些成果，因为这些成果涉及煤炭工业和更广泛的能源界。正如我们过去所做的那样，我们将继续侧重于政策方法和技术，包括高效率、低排放（HELE）燃煤发电厂和碳捕获、利用和储存，使煤炭在一个碳约束的世界中得到利用。

A s this issue of Cornerstone goes to press, world leaders are meeting in Paris, France, for the COP21 negotiations under the United Nations Framework Convention on Climate Change. Momentum for the meetings has long been building, and future issues of Cornerstone will cover the outcomes, as they pertain to the coal industry and the broader energy community. As we have done in the past, we will continue to focus on policy approaches and technologies—including high-efficiency, low-emissions (HELE) coal-fired power plants and carbon capture, utilization, and storage—which enable coal utilization in a carbon-constrained world.
