Dust Simulation and Application of Forced and Exhausted Mixed Ventilation System in Half Coal-Rock Fully-Mechanized Excavation Face

Abstract:

The numerical simulation of migration rule about dust flow field in typical long forcing and short exhausting mixed ventilation dust removal system of half-coal rock fully-mechanized excavation face was carried out, and local ventilation system was improved based on the simulation results. The relative position relationship of ventilation facilities and the matching relationship of forcing and exhausting air volume in half-coal roadway were made sure, thus, the new complete sets of ventilation wet dedusting system with the type of KTCS-500L had been developed. According to the application in Nantun coal mine of Yanzhou mining group, the system proved to be very effective.
