STRATA MOVEMENT WARNING SYSTEM FOR UNDERGROUND MINES

摘要

The strata movement warning system of the present invention provides accurate early prediction of roof fall based on measurement of low frequency micro-seismic waves generated due to strata movement and will be particularly useful for underground mines. The system of the present invention is acoustic sensor based which enables installing of acoustic sensors in any area of underground mine to monitor roof fall and gives warning signal much before the occurrence of actual roof fall by generating audio-visual alarm on occurrence of impending roof fall. The system of the present invention enables installing of acoustic sensors in any area of underground mine to moniter roof fall. The system will effectively enable evacuation of valuable human lives and machine, and taking precautionary measures prior to the actual occurence of roof fall.
