В брошюре рассматривается работа лучших бригад угольной промышленности, рассказывается о приемах высокопроизводительной работы, эффективном использовании горной техники, о развитии социалистического соревнования и о системе обмена передовым опытом в этой отрасли

При строительстве тоннелей закрытым способом вблизи земной поверхности в слабых грунтах на отдельных участках трасс тоннелей применяются технологии проходки, предусматривающие опережающее крепление грунта.

It is not a frequent experience for a write r to receive the opportunity to revise ami update a previous work. Such is the case, however, with this revised second bilition of Introductory Mining Engineering, originally authored by Howar d L. Hurt man. Further , the planned revision took an unexpected turn when Jan M . Millmansky joined the undertaking as coauthor of the second edition. I n fact, I )i Mutmansky contributed to the original work , serving as a reviewer of the  (tillino, as reader, and as critic. He was acknowledged in the preface of the first ilit ion and thus was the logical choice as coauthor of the second edition. <...>

Mining and metallurgical engineering encompasses two major disciplines: mining engineering and metallurgical engineering. Mining engineering separates useful minerals from worthless minerals (often called gangue) or harmful minerals through processes such as mining and mineral processing, or separates multiple useful minerals to obtain raw materials for metallurgy, energy, chemical industry, building materials, and other industries. Mining in a broad sense also includes the extraction of coal, oil, and gas, but this volume mainly focuses on the mining of metal ores. Metallurgical engineering applies the principle of metallurgy to smelt, process, and ultimately obtain metallic materials necessary for human society’s production and human life from the raw materials obtained in mineral engineering.

Coal is an important part of natural resources and the focus of social energy and economic development. With the increase in the energy demand, the amount of coal mining is also increasing, which leads to many safety problems. Improving the elevels of safety in the coal mining process while ensuring that coal production is carried out at an acceptable level is a problem that we must attach great importance to. In this book, we collect, revise and collate the latest work of the main researchers, covering the theory and technology of coal mine disaster prevention and control, safety management and control in the process of coal mining, mineral processing and intelligent/ green mining engineering, mining environmental protection and sustainable development, and other aspects of safety technology research, focusing on coal mine production safety <...>
