Study on Kinetics Characteristics of Coal Gangue Dump Explosion
Based on analyzing the influence factors of coal gangue dump explosion, and combining with the equation of state and energy, the explosive mechanisms and the kinetics characteristic of coal gangue dump have been researched. In the process of research g~gue dump explosive, the article have applied chemical thermodynamics theory, calculated explosive pressure of mixture gases in the condition of vapor rate with air is-100, temperature is 1000K, the ratio of pressure is 1. The result shows that: in this condition, the explosive pressure of mixed gas can reach 5.125x 103 MPa, which can correspond with 50％ of the explosive pressure of TNT30％ pasty detonator with the diameter of 80ram and the density of 1.5g/cm3. This research not only provides guidance for coal enterprises to ensure safety of production, but also is the basis for us to understand the danger of the spontaneous combustion of the gangue dump. It has extremely practical significance to seek effective precaution measures for the occurrence of gangue dump explosion.
