چکیده
In order to master effectiveness situation of underground coal mine spray and dust reduction, analyze and improve the process of spray and dust reduction which effect is non-ideal, feasibility of introducing process capability analysis as scientific management method was investigated. Measuring tool was analyzed with measurement system analysis which guaranteed accuracy and precision of measurement data combined with the example of 3302 working face in a coal mine. With effective cooperation of JMP software, process capability analysis was applied to improve effect analysis, assessment and improvement of the spray and dust reduction. The reasons for the insufficient of spray and dust reduction were analyzed. Eventually, pertinence measure was taken to improve the effect of spray and dust reduction and the capacity requirements were satisfied.
