摩托凿岩机是一种轻便、效率较高的凿岩新机具，适应于偏远山区施工。我省各队都有这种凿岩设备，但因废气净化及打水眼问题未解决，过去仅用于平机场、修路和槽探的打眼工作。最近，214队进行了摩托凿岩机废气净化器的试验，取得良好的效果。从试验结果分析，未安装净化器前，硐内CO含量为0.44％，安装净化器后，CO仅为0.022％，降低95％，较国家规定标准0.0016％尚高13.75倍。根据安徽332队的经验，坑内机械通风，可使CO含量降
Motor rock drill is a light, high efficiency drilling new equipment, adapted to the construction of remote mountainous areas. All teams in our province have this rock drilling equipment, but in the past, it was only used for drilling at the airport, road repairing and slot drilling due to the problem of exhaust gas purification and water fuming. Recently, 214 teams carried out motorcycle rock drill exhaust gas purification test, and achieved good results. According to the analysis of the test results, before the purifier is installed, the content of CO in the tunnel is 0.44%. After the purifier is installed, the CO is only 0.022% and decreased by 95%, which is 13.75 times higher than the national standard of 0.0016%. According to the experience of Anhui 332 team, pit mechanical ventilation, CO content can be reduced
