防尘安全管理要求

　　一、矿尘的危害

　　1.煤尘能燃烧与爆炸，使矿井遭到破坏，造成大量人员伤亡。

　　2.矿尘职业病，悬浮矿尘长期吸人人体，造成肺部组织纤维化病变，使肺部失去弹性，减弱或丧失呼吸能力，以致缩短生命，矿尘职业病又分为煤肺病、煤矽肺病和矽肺病。

　　二、煤尘爆炸及预防

　　1.煤尘爆炸的必备条件;

　　(1)煤尘本身具有爆炸性。

　　(2)煤尘必须悬浮在空气中，并达到一定的浓度(45-2000克/米3)。

　　(3)有高温热源(一般为650-1050℃)

　　2.预防煤尘爆炸的措施包括防尘措施、防爆措施和隔煤措施。

　　3.矿井综合防尘措施：a、建立完善的防尘洒水管路系统;b、煤层注水;c、喷雾洒水;d、风流净化;e、放炮用水炮泥;f、冲洗巷帮;g、湿式打眼;h、采空区灌水;i、隔爆岩粉棚、水棚、洒岩粉;j、刷白巷道;k、个体防护;1、巷道中的浮煤定期清除。

　　4.掘进井巷和硐室时，必须采取湿式钻眼、冲洗井壁巷帮、水炮泥、爆破喷雾、装岩(煤)洒水和净化风流等措施。

　　5.炮采工作面应采取湿式打眼，使用水炮泥，爆破前后应冲洗煤壁，爆破时应喷雾降尘，出煤时洒水。采煤工作面回风巷应安设风流净化水幕。
