COAL DUST EXPLOSION PREVENTION ANALYSIS 53 µM – 44 µM USING LIMESTONE DUST MEASURE 177 µM - 74 µM AND 74 µM– 37 µM THROUGH LABORATORY SCALE TEST

COAL DUST EXPLOSION PREVENTION ANALYSIS 53 µM – 44 µM USING LIMESTONE DUST MEASURE 177 µM - 74 µM AND 74 µM– 37 µM THROUGH LABORATORY SCALE TEST

Coal dust explosion is one of the hazards in coal underground mines. There are five main components that cause coal dust explosions, namely oxygen, fuel (coal dust), heat source, dispersion and confinement. This study aims to analyze the effect of the size and ratio of limestone dust on the pressure...

There are five main components that cause coal dust explosions, namely oxygen, fuel (coal dust), heat source, dispersion and confinement. This study aims to analyze the effect of the size and ratio of limestone dust on the pressure value, the rate of change of pressure and the critical ratio of limestone dust just before the explosion. This study uses a USBM 20-L Explosion Chamber explosive tube with a coal concentration of 600 g/m3 and an ignitor energy of 5 kJ. This test uses limestone dust with a size of 80-200 mesh (177-74 m) and 200-400 mesh (74-37 m) and coal dust with a size of 270-325 mesh (53-44 m). The results of this study stated that the critical ratio for the occurrence of explosions for limestone dust with a size of 177-74 m was found at a rock dust ratio of 55.7%. Meanwhile, for 74-37 m, the critical ratio is found at the rock dust ratio of 54.9%. Meanwhile, in terms of the ratio of coal and limestone dust, the greater the ratio of coal dust compared to the ratio of limestone dust, the greater the pressure and rate of change of coal dust explosion pressure. Based on the size of the limestone, the finer the size of the limestone dust, the lower the pressure and the rate of change of pressure from the coal dust explosion. This is in accordance with previous research that has been done, namely the research of Mishra et al.
