摘要
针对虎龙沟矿21505巷在掘进期间巷道内粉尘浓度大、巷道内能见度低、巷道标准化质量差等难题,对巷道掘进前期防尘措施及问题进行分析,并根据巷道实际生产情况,对传统防尘措施进行优化。通过实际应用效果来看,实施综合防尘措施优化后,使巷道内粉尘质量浓度降低至30 mg/m3以下,能见度提高至30 m以上,取得了显著应用成效。
In view of the technical problems such as large dust concentration,low visibility and poor standardization quality in 21505 roadway of Hulonggou mine during tunneling,the dust prevention measures and problems in the early stage of roadway excavation are analyzed,and the traditional dust prevention measures are optimized according to the actual production situation of roadway.Through the practical application effect,the optimized comprehensive dust prevention measures reduce the dust concentration in the roadway to less than 30 mg/m3,and improve the visibility to more than 30 m,and achieve remarkable application results.
