Overview

The new design of a powered roof support for the controlled longwall top coal caving in thick coal seams contains a special outlet and a reciprocating feeder. The introduction of such technology needs pre-testing and analysis of the outlet modes per the support units, such that to ensure the maximum allowable fill of the longwall conveyor without its overloading and dynamic phenomena. Created in Rocky DEM environment with that end in view, the simulation model takes into account the physical effect of rock mass fracture using the discrete element method, and enables variation in the design parameters and operating conditions of the powered roof support. The implemented experiments make it possible to assess the interdependence of the average velocity of coal outlet to the conveyor, the outlet gate angle and the feeder vibration frequency.
