煤矿井下有五大自然灾害:水 火 瓦斯 煤尘 顶板。除此之外,还有电气,机械。 说到风险,简单点对应说:矿井突水会淹死人;着火会使人一氧化碳中毒(没错,井下发生火灾,中毒死亡的风险比被火烧死大多了);瓦斯爆炸会炸死人,引发火灾和煤尘爆炸;煤尘除了被点燃爆炸,还会被吸入肺里,患上尘肺病;顶板冒落会砸伤或者掩埋人员;电气事故会使人触电,或者引燃火灾;机械事故通常是机械挤压或者打击。
煤矿的五大自然灾害:
1、瓦斯突出与爆炸;
2、煤尘突出怀爆炸;
3、矿井火灾;
4、矿井水灾;
5、顶板事故。
答:不属于。
95%以上的煤矿事故是可以避免的,关键看煤矿企业是否真正重视安全生产工作,安全生产是一项复杂的、涉及很多学科和专业的难题,但大多数煤矿总工程师都知道如何做,不外乎:
1.加强煤矿地质勘查工作,查明地质条件;
2.加强煤矿生产地质工作,包括各类隐蔽致灾因素普查及工程措施,积极落实《煤矿安全规程》、《煤矿隐蔽致灾因素普查技术规范》(T/GRM 055—2022)、《煤矿防治水细则》等规范规程的落实;
3.加强科技攻关,煤矿生产中可能遇到的难题,一定要提前布局科研攻关,向陕西煤业化工集团公司学习,每年定期安排一批科研项目,各煤矿生产单位还可以随时安排科研攻关项目,解决难题,提出灾害防控措施,并落实;
4.加强煤矿生产过程中的监测监控,建立完善的矿井水、岩层移动、顶板变形、瓦斯与煤尘、巷道稳定性、露天边坡变形等监测监控系统,实时掌控各类监测数据,并做好预警;
干旱、高温、低温、寒潮、洪涝.
自然灾害是指给人类生存带来危害或损害人类生活环境的自然现象,包括干旱、高温、低温、寒潮、洪涝、积涝、山洪、台风、龙卷风、火焰龙卷风、冰雹、风雹、霜冻、暴雨、暴雪、冻雨、大雾、大风、结冰、霾、雾霾、浮尘、扬沙、沙尘暴、雷电、雷暴、球状闪电等气象灾害;火山喷发、地震、山体崩塌、滑坡、泥石流等地质灾害;风暴潮、海啸等海洋灾害;森林草原火灾和重大生物灾害等.
煤矿的五大灾害是瓦斯、煤尘、水、火和顶板灾害。
1.瓦斯是指井下各种有毒、易燃易爆的气体;
2.煤尘是指能爆炸的煤尘和浓度达到可以导致尘肺的煤尘;
3.水是指可以导致煤矿淹井或出现人员伤亡的涌水或透水;
4.火是泛指井下发生的各种火灾;
5.顶板灾害是指煤矿巷道或采区顶上的岩层发生的各种垮塌或冒落事故。
通常指的是煤与瓦斯突出、煤尘爆炸和地质构造活动。这些自然灾害都会对煤矿生产造成严重的威胁,可能导致煤矿事故发生。
1. 煤与瓦斯突出:在采掘煤矿时,由于地下压力的变化会引起煤层中的瓦斯逸出,当瓦斯压力快速降低时,会引起周围岩体的破裂和抽采,从而形成煤与瓦斯突出。煤与瓦斯突出是煤矿事故中最为严重和常见的一种,容易导致人员伤亡和财产损失。
2. 煤尘爆炸:在采掘过程中,煤炭会散发出大量的煤尘,如果这些煤尘遇到火源可能会引起煤尘爆炸。煤尘爆炸是煤矿事故中最为危险的一种,具有迅速、强烈、广泛的特点,可以瞬间造成严重人员伤亡和财产损失。
3. 地质构造活动:地震、地壳运动等地质构造活动可能会引起煤矿内部结构变化,导致煤层移位、破裂等情况,从而威胁到煤矿的安全生产。
