This paper studies the reliability of magnetotelluric (MT) method detection for overburden failure (OF) height in shallow seam mining. According to the geological conditions of the 52,505 working face in the Daliuta mine, five observation lines have been designed to detect the apparent resistivity (AR) of the overburden before and after mining ...

Mine Overburden Dump Failure: A Case Study
Geotechnical and Geological Engineering, 2013In any open cast mine, the management of stripped spoil during mining is crucial to the mine’s successful operation. The improper management of the overburden (OB) dump can result in stability issues which may affect safety and production of the mine. Various literatures have reported the failure of open pit dumps and the consequences in loss of life ...

Effect of tunnel overburden stress on the rock brittle failure depth
Arabian Journal of Geosciences, 2019Tunneling under high overburden stresses results in many tunnel instability problems due to the rock overstressing. Understanding and simulating the rock failure process is the major issue of a deep excavation to achieve an appropriate rock support system that provides possible cost-effective and stable construction.

Numerical Simulation of Failure of Overburden in Coal Mining under Reservoir
Advanced Materials Research, 2011The Water-flowing fractured zone’s height and its distribution has an important effect on stability of the surrounding rock and the safety in the subsequent production under reservoir. In the paper the Drucker-Prager yielding law is used. The limit value of tensile stress and shear stress is used to judge the water-flowing fractured zone’s height and ...

Mining with Filling for Mitigating Overburden Failure and Water Inrush Due to Coalmining
2014This paper investigates the heights of overburden failure with cut-and-fill mining method using empirical formula, scaled model tests and numerical simulations. An equivalent cutting height was proposed for calculating overburden failure with formulas and from measurement data. Scale model tests and numerical simulations show that the heights of caving
