Abstract: Based on the proposed ray-tracing based radio waves propagation (RTRWP) Law for complex coal mine workface tunnels, the energy consumption model evaluation is derived. Theoretical analysis about calculating the multiple reflections of the radio waves in coal mine workface is also provided. Simulations and field tests in coal mine workface tunnels show that the proposed RTRWP law is suitable to describe the actual radio wave propagation in coal mine workface.

 

Keywords: Coal mine workface, Ray-tracing based radio waves propagation (RTRWP) law, Multi-path model, Energy loss.
