Analysis of the Coal and Gas Outburst Mechanism from the Perspective of Tectonic Movement
Coal and gas outburst is the extreme instability caused by stress, gas, and coal. In this review article, dominant factors and inducing factors of outburst were summarized; geologic features of typical outburst cases and the effects of tectonic movement ...

Mechanism for stress abnormality and rock burst in variation zone of roof-stratum thickness
The roof stratum structure is one of the main factors affecting coal burst, and the coal burst is also easily induced in the variation zone of roof-stratum thickness. This phenomenon is gradually severe in deep mining areas in Inner Mongolia.

PRESENTDAY STRESS STATE OF THE SHANXI TECTONIC BELT
The Shanxi tectonic belt is a historically earthquakeabundant area. For the majority of strong earthquakes in this area, the distribution of earthquake foci was controlled by the N–S oriented local structures on the tectonic belt.

Case Studies of Rock Bursts in Tectonic Areas with Facies Change
Although tectonic areas with facies change (i.e., variation of coal seam thickness, coal seam dip angle, or coal quality) are one of the three major geological structures that induce rock bursts, case studies of rock bursts in these tectonic structures ...

Earthquake Predicting and Tectonic Stress Reducing Possibilities
Abstract Recent satellite and ground-based observations prove that during the earthquake formative period VLF/LF and ULF electromagnetic emissions are observed in seismogenic areas. The present consolidated paper describes a theoretical model of the generation of electromagnetic emissions detected during the earthquake preparation periods, a ...

Geochemistry and tectonic development of Cenozoic magmatism in the Carpathian–Pannonian region [PDF]
This review considers the magmatic processes in the Carpathian–Pannonian Region (CPR) from Early Miocene to Recent times, as well as the contemporaneous magmatism at its southern boundary in the Dinaride and Balkans regions.

In order to establish the methodology of hydraulic fracturing tectonic stress measurements, the relation between the so-called reopening pressure of longitudinal cracks and tectonic stresses is studied. To this end, the coupled problem of fluid flow in the crack and the crack reopening behavior in an impermeable rock is analyzed based on the linear ...
