Abstract
There were analyzed the methods of quality control of neutralization of explosive properties of dust (quality of rock dusting) based on 3 physical principles of measurement: optical, radioisotope and chemical ones. There are considered advantages and disadvantages of both control methods and industrial devices implemented on the corresponding physical principles. There is proposed fundamentally new thermogravimetric method for assessing the quality of rock dusting of mine workings, as well as the main parameters are described.
