摘要

Explosion of high-sulfur gangue pile with spontaneous combosting potential is a difficult problem in coal mines. Frequent explosion accidents not only affected production of coal mine, but also affected atmospheric environment quality. Especially, it severely impaired farming, forestry, herd and human beings around gangue.piles, all which lead to massive personnel casualty and economic loss. Thus, coal mines rapid development was blocked. It has vital significance to study the measures of explosion control of high-sulfur gangue pile with spontaneous combusting potential. Basing on the site status of gangue piles, experiment of primer control factors was carried on for explosion of high-sulfur gangne pile with spontaneous combusting potential from the following aspects:, sulfur content, moisture content and porosity ratio. Experiments show that: average temperature rising velocity were decreased along with the decrease of sulfur content, it is 0.23 °C/min, 0.15°C/rain and 0.08 °C/min respectively. Pyrite oxidization makes great contribution to the gangue temperature rising, spontaneous combustion will easily occur with high content of pyrite, because it causes the temperature rising rapidly. In the different moisture content experiment, average temperature rising velocity were 0.18 °C/min, 0.17 °C/rain, 0.17 °C/min respectively, the difference is not remarkable, but the rule is complex, moist gangne is obviously faster than the dry gangue, after the water was evaporated, the temperature rising is almost at same velocity. In the different porosity content experiment, average" temperature rising velocity were 0.21 °C/min, 0.25 °C/min, 0.18 °C/min respectively, the influence of oxidation and temperature rising for gangue is distinct among different porosity, it also affect the interior oxygen density and regeneration environment, which are pair of contradictory spontaneous combustion influencing factors, the porosity is mutually bigger, the gangue mountain interior oxygen content increases, but simultaneously the transfusion strengthens, which does not favor the regeneration, the porosity is smaller, the regeneration environment is better, but which cannot guarantee the enough oxygen supply.
