Failure characteristic and fracture evolution law of overburden of thick coal in fully mechanized sub-level caving mining

, 2017
In mining process, the height of water flowing fractured zone is important significance to prevent mine of water and gas, in order to further research the failure characteristic of the overlying strata.

Face Length Optimization in Mechanized Retreating longwall Method

, 1997
Longwall panels, where geologically possible, are becoming larger everyday. The increase in size is limited by rock mechanics and economic factors . In a caving longwall panel, as the face length increases, pressure exerted on the edges of the entries on
