Research in Short-Range Sensing of Non-Metal Object in Coal Mine Underground

Abstract

Abstract

In the paper a short-range non--metal object sensing technology of capacitance detection is described, which can be used in a wide range, detecting proximity of roof rock and coal, coal level for belt conveyor, coal stack at conveyor head and coal bunker level, air door position, belt misalignment.
