A fuzzy comprehensive evaluation methodology for rock burst forecasting using microseismic monitoring
TL;DR: In this paper, a methodology for rock burst forecasting involving the use of a fuzzy comprehensive evaluation model was developed, which allows for a more quantitative evaluation of the likelihood for the occurrence of a rock burst incident.
Journal ArticleDOI
Effective evaluation of pressure relief drilling for reducing rock bursts and its application in underground coal mines
TL;DR: In this paper, a series of experimental studies on mechanical properties are conducted using gypsum-type coal-like materials with different numbers and configurations of pressure relief boreholes, and the change in parameters, such as the strength and energy dissipation index of bored coallike materials under a uniaxial compression, is studied, and fracture propagation characteristics in the rock surrounding the boreholes in the experiments are analyzed.

The current situation and prevention and control countermeasures for typical dynamic disasters in kilometer-deep mines in China
TL;DR: Wang et al. as mentioned in this paper analyzed the status quo of mining and typical dynamic disasters currently for 47 deep mines in China, and found that the 47 mines are mainly distributed in 8 provinces; the proportions of mines affected by rock burst and coal and gas outburst are 53.2% and 29.79%, which are 29.23 times and 2.66 times the national average.

Bursting liability indices of coal
TL;DR: In this paper, several indices have been proposed and their numerical values found by experiment in order to classify the potential liability of coal seams to create rock-burst hazards, namely the strain energy storage index (W ET ), the Bursting Efficiency Ratio (η), and the Rheologic Ratio (ϑ).

Coal mine ground control
TL;DR: Mine Layouts and ground control practices in underground coal mines Common Ground Control Problems in Underground Coal Mines Rock Properties and in situ Stresses Geological Effects and Roof Stability Classification and Investigation Roof Bolting Coal Pillars Ground Control in Longwall Mining Ground Control and Multiple-Seam Mining Bumps Instrumentation Special Supports and Problems Surface Subsidence Appendixes as discussed by the authors
Journal ArticleDOI
Seismic moments and volume changes
TL;DR: In this paper, the relationship between seismic moment and volume change was analyzed to analyze earthquake sequences resulting from ground deformation that could most easily be described as volume changes, and the results showed that the change in volume is accommodated only by seismic failure.

A review of mining-induced seismicity in China
T. Li,Meifeng Cai,Ming Cai +2 more
TL;DR: In this article, the authors reviewed the distribution and characteristics of mining-induced seismicity in China, and its monitoring, mitigation, and research, and found that the key problems of rockburst hazard mitigation in China are the lack of mine seismicitymonitoring networks in most mines, and the need for improvement of the accuracy of the monitoring systems for mines that have been equipped with such systems.
