The Experimental System For Mine Ventilation Control

The experimental system for mine venti1ation control in Staszic colliery has two - level structure. In the lower - measuring 1evel the existing computer - based early fire detection system has been used completed with a number of additional sensors needed for ventilation parameters monitoring. The higher 1evel is a secondary computer equipped with a suitab1e dedicated software performing data processing according to the control a1gorithm. Direct control of air flow in a selected mine district is performed by means of a remotely controlled automatic regulator. Apart from functional tests of the system and its elements some research work has been carrying out in the colliery based on observations of transient effects caused by changes in air flow distribution.
