Fault coal bursts is a common type of in mining. With increases mining depths and intensities, the occurrence frequency disaster degree fault-controlled areas are increasing severity. Therefore, this article, mechanism control method deep mining-induced fault analysed on No. 3402 longwall panel controlled by two faults Shandong Mine, China. Based microseismic monitoring data panel, activation p...

Firstly, we wish to acknowledge the leadership and contribution that Smith and his various coworkers have made over the last three decades to the understanding of the origin of natural gas and coal seam gas, particularly through the use of stable isotopes. Our intention was in no way to criticise their views. Rather, as expressed in Boreham et al. (1998) our view was and remains ``that the orig...

Modern underground coal mining requires certainty about geological faults and other structural features for safety reasons. Even a fault with a throw of a few metres can create safety issues and lead to costly delays in mine production. To ensure there are no unwelcome surprises concerning seam conditions during mining, seismic reflection surveys have been widely used by Australian coal mines, ...

Monitorovanie a riadenie podzemneho splyňovania uhlia v laboratórnych podmienkach A number of coal gasification technologies are currently available or under various stages of development. One technology “Underground coal gasification (UCG)” is receiving renewed interest around the world. In this paper is provided the analysis of relevant processes during UCG. The laboratory equipment is descri...

Automation in underground mining enhances safety and leads to economic efficiencies. After more than 50 years of research, automation tasks have gradually been growing out of the classic engineering/mechanical environment and require a sophisticated datamining treatment. The success of (mechanical) process automation has left only one remaining place in the coal-excavation process where human l...

This paper discusses the content, distribution, modes of occurrence, and enrichment mechanism of mineral matter and trace elements of an Early Permian coal from Songshao (Yunnan Province, China) by means of coal-petrological, mineralogical, and geochemical techniques. The results show that the Songshao coal is characterized by high total and organic sulfur contents (3.61% and 3.87%, respectivel...

The influence of sorption-induced coal matrix deformation on the evolution of porosity and permeability of fractured coal seams is evaluated, together with its influence on gas recovery rates. The porosity-based model considers factors such as the volume occupied by the free-phase gas, the volume occupied by the adsorbed phase gas, the deformation-induced pore volume change, and the sorptionind...

China is the world’s largest coal-producing country and mining-related land subsidence happens almost in every coal mining area. In north-west China, land subsidence in coal mining areas is mainly caused by underground mining activities and uncontrolled burnings of subsurface coal seam. As Hoffmann (2004) reported, burning coal-seams can result in extensive subsidence of several meters and typi...
