地质构造复杂采煤工作面防灭火技术应用

Application of fire prevention and extinguishing technology in coal face with complex geological structure

单侯矿5301工作面地质条件复杂,在回采过程中过断层时会有大量煤炭丢于采空区,且具有自然发火的隐患。通过类比法判断出5301工作面采空区"三带"的大致宽度,并采取了综合防火措施。结果表明,同一矿井同一煤层不同采区的工作面地质条件差异不大时,可以采取类比法判断出采空区宽度并采取有针对性的综合防灭火措施。

Based on complex geological conditions in 5301 working face of Shanhou Mine,a large amount of coal was wasted in goaf,with hidden fire disster,the width of three belts was settled,the comprhensive fire prevention and control technology was adopted.The result showed that analogism could be adopted to judge goaf width with corresponding fire prevention and control technology in same coal seam with similar geological conditions.
