基于逐点气压计测定法的煤体自燃防治研究

Study on Prevention and Control of Coal Spontaneous Combustion Based on Point-by-point Barometer Measurement Method

为了预防煤体自燃现象的发生,基于逐点气压计测定法分析了紫晟煤业矿井通风现状,通过Fluent仿真模拟软件对矿井不同区域进行了研究,发现隔离煤柱区域具有自燃倾向性。通过采取灌浆防灭火措施,有效预防了该区域煤体的自燃。

In order to prevent the occurrence of coal spontaneous combustion,based on the point-by-point barometer measure-ment method,this paper analyzed the current situation of mine ventilation in Zisheng Coal Industry Co.,Ltd.,studied different areas of the mine through Fluent analogue simulation software,and found that the isolated coal pillar area had the tendency of spontaneous combustion.By taking grouting fire prevention measure,the spontaneous combustion of coal in this area was effec-tively prevented.
