Study on the Monitoring Method of Overburden Failure of Shallow Wongawilli Mining Working Face
Advanced Materials Research, 2011Through the practice and improvement of Wongawilli Mining method in Shendong Mining Area, it created Shendong Characteristic short wall mechanize room mining method. Due to the shallow coal seam, the fracture zones throughout the bedrock directly after the mining, therefore the bending sinking belt didn’t exist; the conventional "three zones" theory ...

Rock Mechanics and Rock Engineering, 2016
To reveal the mechanical response of a multi-pillar supporting system under external loads, compressive tests were carried out on single-pillar and double-pillar specimens. The digital speckle correlation method and acoustic emission technique were applied to record and analyse information of the deformation and failure processes. Numerical simulations

Statistical Prediction of Overburden Failure Due to Coal Mining Under Sea Area
2013This paper presents a statistical prediction of the height of water flowing fractured zone due to coal mining under sea area. Some field measurement methods were used in the Beizao, Liangjia, Wali and Huangxian Coalmines in Shandong Province, China, to investigate the failure process and the maximum height of water flowing fractured zone under ...

Lost production costs of the overburden excavation system caused by rubber belt failure
2012In this paper the average malfunction costs (lost production) of the overburden excavation system on the Tamnava - East field open-pit mine caused by the failure of belt conveyor rubber belts which work on the bucket wheel excavator, belt wagon and spreader are determined, i.e.
