Study of the parameters of spontaneous fire seats in coal pit rock dumps

The presence of coal and coal-bearing rocks in waste rock dumps open-pit mines contributes to the occurrence spontaneous combustions that negatively affect environment people. Measurements temperature content hazardous gases anomaly arose dump mine were made assess parameters fire seats. In course study, efficiency detecting seats was assessed by measuring wells with a depth 2.5 m, drilled at distance 20 m from each other. experiment showed difficulty drilling control impossibility them on slopes dumps, especially high temperature. necessity casing pipes makes it difficult measure different depths. It found there are sharp drops heated area dump, which cannot be detected when located recommended distance. measurements all increases depth, therefore regulatory documents does not allow determining size area.
