This book investigates in detail the theory and method of automatically formed mining roadway (AFR). The AFR method utilizes mining pressure and broken expansion characteristics of the collapsed rock mass in the gob to automatically form roadways, which changes the traditional “long cantilever beam” to “short cantilever beam” structure, and eliminate roadway excavation and coal pillar reserve. Key technologies are developed under the guidance of the “equilibrium mining” theory, such as in situ drilling and zoning technology, roof directional presplitting technology, high prestressed constant-resistance support technology, and gangue blocking support technology. The mining technologies and methods are successfully applied to a large number of coal mines of different geological conditions. The book is intended for both researchers and practitioners working in the mining, civil, and geological engineering fields.

This book provides a detailed introduction to the mechanism of rockburst in extremely thick coal seam mining and explores the mechanical mechanism on why the critical depth of rockburst in extremely thick coal seam mining is significantly smaller than that in thin to thick coal seams, it also proposes targeted monitoring, warning, and treatment technologies. The prevention and control of coal mine rockburst is a global problem, attracting engineers and scientists from various disciplines such as mining, geology, geophysics, and civil engineering to conduct research. This book provides multiple case studies of rockburst accidents in mining of ultra-thick coal seams and provides a detailed analysis of the mechanisms and treatment technologies of each rockburst accident. It aims at graduate students, researchers, and on-site engineers who are interested in the mechanism of rockburst occurrence, monitoring, early warning, and treatment technology. The translation was done with the help of artificial intelligence. The present version has been revised technically and linguistically by the authors in collaboration with a professional translator.

This Research Topic is Volume II of a series. The previous volume can be found here: Coal and Rock Dynamic Disasters: Advances of Physical and Numerical Simulation in Monitoring, Early Warning, and Prevention With the soaring growth of global population and socioeconomy, energy consumption and demand has been rapidly rising, and coal would still remain a fundamental energy source for a long time into the future. Seeking deep coal resources becomes an inevitable trend due to the depletion of shallow coal resources. Deep mining of coal resources promotes socioeconomic development, whereas bringing a variety of security challenges. In deep underground, there is a significant risk increase in coal and rock dynamic disasters (CRDDs), owing to the changes in physical and mechanical properties of coal and rock. In this regard, it is of great importance and necessity to prevent and control CRDDs effectively and efficiently.

This includes the Proceedings of the international symposium, Abisko, Sweden, 28 August-2 September 1983. Rock bolts today represent the dominant support system in mines and underground structures. Some results and experiences are discussed to give a better understanding of the strength of individual rock bolts and systems of bolts, and the interaction between bolts and rock masses of various types. Topics covered are as follows: rock bolting in theory and experiments; design principles and experience; and ground control and instrumentation: cable bolting.

With the increasing demand for infrastructure construction as the global economy progresses, the need for exploration and utilization of deep underground space becomes more crucial. Various deep underground projects are planned, are under construction, and have been built to encounter great construction challenges due to the complex geo-environment such as strong tectonic movement, fragile geo-environment and complex thermo-hydro-mechanical-chemical conditions. These deep engineering projects could be endangered by different kinds of geological disasters, such as intense rockburst, large deformation, strong water inrush, and large-scale collapse, which might result in massive loss of life and economic damage during the construction of deep underground projects. It is necessary to take proactive measures to ensure that the development of deep engineering projects is risk-informed and sustainable. Efforts are being called for strengthening science and technology innovation and cooperation in geological disaster mitigation and sustainable development during the construction of deep engineering projects. It is paramount to use new technologies and international cooperation to jointly tackle the geological disasters risks and achieve sustainable development. To mitigate the risk of geological disaster in deep engineering under the complicate geo-environment, the mechanism of the formation and evolution of geological disasters in deep engineering needs to be understood. The testing, monitoring, simulation, risk assessment and early warning methods for geological disaster in deep engineering are also needed urgently. New theories, methods and techniques related to the mechanism, warning and risk mitigation of geological disasters in deep engineering will be extremely helpful for the construction safety of deep engineering.
