At present, the world is committed to development of environmentally friendly, sustainable and industrial safety. The effective treatment solid waste can be applied in field It one ways apply safety modify combine active powder prepare waste-based composite explosion inhibitors it underground coal dust explosion. This paper introduces modification preparation methods waste, analyzes good suppre...

Coal dust endangers the health and safety of workers in underground coal mines. Therefore, developing suppressants with prevention explosion-proof properties is critical. The influence molasses on explosion decomposition deposited mines was investigated using 20 L experiments thermogravimetric differential thermal analysis (TG-DTA). Findings reveal that, first, can weakly promote at low concent...

Coal dust explosions in underground coal mines are pre­ vented by a generous application of rock dust (usually lime­ stone). If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents fl ame propagation by acting as a thermal inhibitor or heat sink. To investigate this process in more detail, a number of ex­ plosion experiments using various coal dust and limes...

Abstract Isotopic ratios of radioxenons sampled in the atmosphere or subsurface can be used to verify occurrence an underground nuclear explosion (UNE). Differences half-lives radioactive xenon precursors and their decay-chain networks produce different time-dependent concentration profiles isotopes allowing isotopic for tracking UNE histories including estimating time detonation. In this study...
