急倾斜煤层应用综合防灭火法防止煤层自燃发火技术的研究样本

下载后可任意编辑急倾斜煤层应用综合防灭火法防止煤层自燃发火技术的讨论陈广瑞( 新集三矿 安徽 淮南 232100) 摘要: 矿井火灾是煤矿五大自然灾害之一, 严重威胁矿井生产安全。新集三矿开采的煤层均属于易自燃煤层, 且自然发火期短( 3～6 个月) , 开采过程中作业地点移动频繁, 预防内外因火灾的形式同样严峻。新集三矿不断探究和总结急倾斜煤层防灭火技术, 使煤层自燃发火事故明显降低, 保证了矿井的安全生产。关键词: 煤层自燃 注氮 注浆 漏风区中图分类号: TU45 文献标识码: A 文章编号: Steeply inclined coal seam application of comprehensive fire prevention and extinguishing technology of preventing coal seam spontaneous combustion researchCHEN guang- rui (SDIC XINJI ENERGY COMPANY LIMI, ANHUIHUAINAN, CHINA, 232100,Email: )Abstract: the coal mine fire is one of the five natural disasters, serious threat to safe production in mines, coal mine three coal mining are now easily spontaneous combustion coal seam, and spontaneous combustion period is short (3~ 6 months ), work place moves frequently, prevention and for fire form the same grim. New set of three mine is ceaseless exploration and summary in steeply inclined coal seam spontaneous combustion fire prevention and extinguishing technology, so that the accident was significantly reduced, to ensure the safety production of mine.Key words: coal spontaneous combustion and nitrogen injection grouting leakage area简介新集三矿位于安徽省凤台县境内, 地处淮河北( 西) 岸, 距凤台县城 4 km。井田内可采及局部可采煤层共 8 层, 分别为 1 煤、 3 煤、 6-1煤、 8-1煤、 8-2煤、 11-2煤、 13-1煤和 14 煤。井田东以淮河为边界, 西到Ⅸ勘探线以西 1300m 处, 南以 1 煤底板为界, 北至 14煤层, 东西走向长 8.6km, 南北倾斜宽 0.79km, 井田面积 6.8174km2。受区域推覆构造影响, 下载后可任意编辑矿井总体构造呈轴向近东西的不对称倒转褶曲形态, 上部正常翼倾向北, 倾角 60～90°, 下部全倒转翼倾向南, 倾角多为 20～30...
