Book Description
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researchers tend to favor recent developments when performing a literature search, ignoring or considering old papers outdated.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.

Book Description
The main objective of MapROC project has been to field test and develop a number of rock burst and gas outburst prevention techniques based on stress and pressure relief principles and evaluate their performance through continuous microseismic monitoring at mine sites. It was established that large diameter stress and gas pressure relief boreholes used at barrier pillars, and the borehole blasting practices extensively tested at Coal Mine Velenje were very effective. As a result, these measures have now entered in Coal Mine Velenje's statutes and will be implemented at all development sites against increased rock burst hazards. Extensive field microseismic monitoring carried out at two mines and near-real-time assessment of this data on a weekly basis led to the development of a number of risk assessment techniques which were validated for their future use by the industry. A catalogue of short term risk evaluation models aiming at forecasting the risk levels of rock bursts and coal and gas outbursts in terms of different evaluation indices. Furthermore, a number of numerical modelling methods were also developed and validated. Utilising all the learnings from MapROC, a generic risk assessment methodology was developed and validated using to a representative number of mining scenarios utilising site-specific data and the laboratory and field studies conducted in the MapROC project. The generic methodology is believed to be applicable to most European coal mines with different geological and mining conditions. The state-of-the-art best technologies report describing the monitoring, assessment, prevention and mitigation of rock burst and gas outburst hazards in coal mines can be used by the industry in Europe and internationally.

Book Description
This paper summarizes past observations of outbursts in the coal mines of the Sydney field, Nova Scotia, along with research conducted to investigate the causes of the outburst phenomena. It also describes the intrinsically safe microseismic monitoring system installed at the Phalen mine, including design criteria, sensors, hardware, and software, along with seismic observations & signal processing results.
