Book excerpt: The goal of coal mining is to obtain coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. Coal mining has had many developments over the recent years, from the early days of men tunneling, digging and manually extracting the coal on carts, to large open cut and long wall mines. Mining at this scale requires the use of draglines, trucks, conveyors, jacks and shearers. The most economical method of coal extraction from coal seams depends on the depth and quality of the seams, and the geology and environmental factors. Coal mining processes are differentiated by whether they operate on the surface or underground. Surface mining and deep underground mining are the two basic methods of mining. The choice of mining method depends primarily on depth of burial, density of the overburden and thickness of the coal seam. Seams relatively close to the surface, at depths less than approximately 180 ft (50 m), are usually surface mined. Coal that occurs at depths of 180 to 300 ft (50 to 100 m) is usually deep mined, but in some cases surface mining techniques can be used. Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production. This book entitled Coal Mine Ground Control covers every major topic concerned with ground control in underground coal mines, with emphasis on the application of various ground control theories and techniques. The book reviews current general practices in underground mine layouts, roof control, and common ground control failures, and the discussion of the state-of-the-art of coal mine ground control technology. The book will also prove useful to practical engineers involved in either the design or the day-to-day operations of underground coal mines.
Download or read book Developments in Ground Control in Mining 1981 2020 written by Syd S. Peng and published by Society for Mining, Metallurgy & Exploration. This book was released on 2022-06-03 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: The best of ground control technology, 40 years in the making. Developments in Ground Control summarizes the objectives, methodology used, and major conclusions reached from papers presented and published in the International Conference on Ground Control in Mining (ICGCM) proceedings from 1981 to 2020. Because the subject areas of the papers published in the proceedings are so broad, ranging from accident training and coal/rock bursts to geology, pillar, multiseam mining, in situ stresses, roof falls, and roof supports to surface subsidence, the papers were grouped into 13 aggregate topics and addressed separately in 13 book chapters by 13 authors from 4 countries. These book chapters are a fresh look at the topics, providing new insights, sourcing older papers, and summarizing data. This is an enormous help for those seeking information on ground control. There were 1,795 papers in the 40 years of ICGCM proceedings in more than 40 ground control topical areas. It would certainly be very time consuming if not impossible to find the right papers of interest in a timely manner. This book makes it easy for interested people to find the progress, application, and achievements of certain techniques from the past 40 years and how they affected the field of ground control and the world mining industry, in particular, the United States. Generally speaking, most researchers tend to favor recent developments when performing a literature search, ignoring or considering old papers outdated. In contrast, over the last 40 years, most research findings for a specific topic in ICGCM received continuing attention for subsequent development or repeated citations if applications were successful.

This book was released on 2016-02-02 with total page 693 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book teaches readers ground engineering principles and related mining and risk management practices associated with underground coal mining. It establishes the basic elements of risk management and the fundamental principles of ground behaviour and then applies these to the essential building blocks of any underground coal mining system, comprising excavations, pillars, and interactions between workings. Readers will also learn about types of ground support and reinforcement systems and their operating mechanisms. These elements provide the platform whereby the principles can be applied to mining practice and risk management, directed primarily to bord and pillar mining, pillar extraction, longwall mining, sub-surface and surface subsidence, and operational hazards. The text concludes by presenting the framework of risk-based ground control management systems for achieving safe workplaces and efficient mining operations. In addition, a comprehensive reference list provides additional sources of information on the subject. Throughout, a large variety of examples show good and bad mining situations in order to demonstrate the application, or absence, of the established principles in practice. Written by an expert in underground coal mining and risk management, this book will help students and practitioners gain a deep understanding of the basic principles behind designing and conducting mining operations that are safe, efficient, and economically viable.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ground hazards are a major safety concern in underground mines, causing deaths, injuries, and lost work time to miners. Although ground hazards such as roof fall accidents have steadily and significantly declined over the last decade, the safety hazards associated with ground hazards still account for a significant portion of the total number of accidents in the underground mining industry. One of the main reasons behind ground hazards in underground mines is abrupt changes in geological conditions that may decrease the competence of the rocks surrounding an excavation, resulting in ground failure. The changes in geological can be detected in a mined-out area, and a possible roof fall accident can be avoided if prompt countermeasures are taken, but changes cannot be easily foreseen in unexcavated areas. An obvious solution to this issue would be to predict strata geological conditions in advance of mining, followed by risk assessment and design of a safe and cost-effective ground support system. The prediction of geological conditions plays a vital role in mine planning and design. It is significantly important for the mine workers’ safety and could be economically attractive in terms of increased productivity and reduced production loss. However, predicting changes in geological conditions in unexcavated areas is a complex task, and it requires proper mine strata characterization and mine design. This research aims to address ground control issues in the mining industry by utilizing Artificial intelligence (AI) techniques to predict lithology and RQD based on the location input data ( x, y, and z coordinates). The accurate prediction of lithology and RQD is crucial for effective ground control management in mining operations. The methodology developed in this research involves the creation of a predictive model using various machine learning algorithms. The input dataset is comprised of drill hole x, y, and z coordinates, and the outputs are lithology and the RQD. The model was trained, optimized, and validated using a large set of drill hole data from an underground metal mine. The results show that the random forest (RF) model performed better than other models, with a prediction accuracy of 98%. The trained model was used to build an interactive-user interface. By inputing just any location x,y, and z coordinates within the mine, into the interface, authorized users can get output of lithology and RQD for that location. This research may help improve the accuracy and the efficiency of ground control management practices in the mining industry, as well as economically benefit the industry.
