西曲矿综采工作面粉尘在线监测自动降尘装置应用研究

Application of On-line Monitoring and Automatic Dust Suppression Device in Fully-mechanized Mining Face in Xiqu Mine

针对煤矿综采工作面降尘效果不理想,无法对工作面现场粉尘浓度进行实时检测并有效降尘的情况,提出了应用ZP-127型粉尘在线监测自动降尘装置,对现场粉尘浓度自动分析,并且当粉尘浓度超过一定限值后进行自动喷雾降尘措施。该系统在山西西曲煤矿18502综采工作面试用后的降尘效果较为明显,大大减少了现场粉尘浓度,使工人工作环境得到了显著改善。

Because of poor dust suppression effect in fully- mechanized mining face, real- time monitoring of dust concentration and effective dust suppression cannot be realized on- site. The paper proposes an on- line monitoring and automatic dust suppression device, ZP- 127, to automatically study the dust concentration on- site and to conduct some measures as automatic spray and aspirating after the dust concentration exceeds the limit. The system was used in No.18502 fully- mechanized mining face in Xiqu mine, which achieved obvious dust suppression effect, reduced the dust concentration, and improved the working environment.
