煤矿井下火灾防治技术 | 2011-9-2 7:16:00

1  揭露新煤层时,建设单位必须对煤层的自燃倾向性进行鉴定。(煤矿安全规程第228修改)

2  在容易自燃和自燃的煤层中施工时,必须对突出和冒落孔洞等空隙采取灌注泥浆或全部充填、喷洒阻化剂、注阻化泥浆、注凝胶等措施,编制相应的防灭火设计,防止自然发火。(煤矿安全规程第232修改)

3  采用阻化剂防灭火时,应遵守下列规定:(煤矿安全规程第235条)

a)  选用的阻化剂材料不得污染井下空气和危害人体健康;

b)  必须在设计中对阻化剂的种类和数量、阻化效果等主要参数作出明确规定;。

c)  应采取防止阻化剂腐蚀机械设备、支架等金属构件的措施;

4  采用凝胶防灭火时,应遵守下列规定:(煤矿安全规程第236条)

a)  选用的凝胶和促凝剂材料,不得污染井下空气和危害人体健康,使用时井巷空气成分必须符合本规范6.2.1.2的有关规定;

b)  编制的设计中应明确规定凝胶的配方、促凝时间和压注量等参数;

c)  压注的凝胶必须充填满全部空间,其外表面应予喷浆封闭,并定期观测,发现老化、干裂时,应予重新压注。

5  在容易自燃和自燃的煤层中施工时,必须明确选定自然发火观测站或观测点的位置并建立监测系统、确定煤层自然发火的标志气体和建立自然发火预测预报制度。所有检测分析结果必须记录在专用的防火记录簿内,并定期检查、分析整理,发现自然发火指标超过或达到临界值等异常变化时,立即发出自然发火预报,采取措施进行处理。(煤矿安全规程第241条)

6  在容易自燃和自燃的煤层中掘进巷道时,对巷道中出现的冒顶区必须及时进行防火处理,并定期检查。(煤矿安全规程第243条)

7  任何人发现井下火灾时,应视火灾性质、灾区通风和瓦斯情况,立即采取一切可能的方法直接灭火,控制火势,并迅速报告调度室。调度室在接到井下火灾报告后,应立即按应急预案通知有关人员组织抢救灾区人员和实施灭火工作。(煤矿安全规程第244条)

值班调度和现场区、队、班组长应按应急预案规定,将所有可能受火灾威胁地区中的人员撤离,并组织人员灭火。电气设备着火时,应首先切断其电源;在切断电源前,只准使用不导电的灭火器材进行灭火。

抢救人员和灭火过程中,必须指定专人检查瓦斯、一氧化碳、煤尘、其他有害气体和风向、风量的变化,还必须采取防止瓦斯、煤尘爆炸和人员中毒的安全措施。

8  封闭火区灭火时,应尽量缩小封闭范围,并必须指定专人检查瓦斯、氧气、一氧化碳、煤尘以及其他有害气体和风向、风量的变化,还必须采取防止瓦斯、煤尘爆炸和人员中毒的安全措施。

(煤矿安全规程第245条)
