Gas explosions are the biggest threat to coal mine safety, which often result in sudden massive destruction. When a gas explosion occurs mine, it causes large number of casualties and property losses, significantly restricts development industry. In this study, numerical model was established for excavation main roadways under condition forward blasting chamber wall, law overpressure propagation flame temperature were studied. The results show that curve first increases then decreases with...
Monitoring the temperature to determine fire source locations is essential for controlling spontaneous combustion in goaf. Optical fiber sensors are employed measure distribution However, due changes geological conditions and influence of falling rocks goaf, only on upper side uncompacted inclination coal pillar, may remain. Unilateral located while occurs center. To investigate issue with linear unilateral sensors, a two-dimensional inverse method has been developed location sources by...
