摘要:
针对施工过程中逸出易燃气体的季家坡隧道内各预设监测断面测点进行有害气体成分及浓度监测,并凿超前孔进行孔口瓦斯及其他有害气体检测.通过对监测数据进行分析得出,已经开挖隧道沿程空气瓦斯浓度(体积分数,下同)为0.1%~0.2%,属于安全作业区.而在掘进掌子面,尽管隧道正常通风,其上部区域瓦斯浓度仍为4.6%~5%,属于高风险作业区;隧道前方地层是高浓度、低压力的瓦斯赋存.提出了加强通风、施工全过程安全监测、加强施工安全管理的建议.
Abstract:
This paper presents the monitoring result of the ingredients and concentration of the harmful gases at the presetmonitoring points of the sections in the Jijiapo Tunnel where flammable gases run out in construction process. In addition, advance bores are drilled to detect the methane and other hazardous gases. According to analysis of the monitoring data,this paper concludes that the gas concentration is 0.1%-0.2% along the tunnel excavated that belongs to safe work zone, while the gas concentration at 4.6%-5% at the tunneling working face belongs to highrisk work zone of gas emission although normally ventilated,and the layer of rock in front of the tunnel is occurrence of gas with high concentration and low pressure. This paper puts forward some advice for enhancing ventilation,risk monitoring during whole the process of construction and strengthening safety management.
