针对煤矿掘锚工作面生产作业时粉尘浓度高、作业环境差、通过通风工艺不能高效、快速排除粉尘这一现状,提出了在掘锚工作面安设干式除尘设备进行粉尘治理的方案。通过该干式除尘器在寸草塔二矿31203输送带工作面半年多的应用实践,在粉尘治理方面效果极其显著,除尘效率达90%以上,有效改善了工作面的作业环境,特别是与现有桥式转载系统配合使用,除尘器可以随工作面输送带延伸时及时跟进,无需频繁倒设,一次安装,长期使用。实践表明,此新型除尘设备具有移动方便、操作简单、便于维护、节能环保、除尘效率高等特点。
In the light of the high dust concentration and poor working environment during coal mine digging and anchor working face production, the dust control is put forward by installing dry dust removal equipment at the digging and bolting face through the ventilation process which can not remove dust quickly and efficiently. Through the application of the dry dust collector in the operation of 31203 conveyor belt of the Incaotome No.2 Mine for more than six months, the effect of the dust control is extremely remarkable. The dust removal efficiency reaches over 90%, effectively improving the working environment of the working face, With the existing bridging system, the dust remover can follow up with the extension of the conveyor belt on the working face without the need of frequent down-setting, once installation and long-term use. Practice shows that this new dust removal equipment has the advantages of easy movement, simple operation, easy maintenance, energy saving and environmental protection, high dust removal efficiency and the like.
