针对汝箕沟矿区露天开采,受小窑火区的影响,钻孔施工后温度过高,无法正常装药爆破,严重延缓了露天矿生产;钻孔高温以及火区产生有毒有害气体威胁作业人员的生命安全。特构建综合防灭火系统,利用注浆、注水、注三相泡沫等综合快速治理技术,提高火区爆破、剥离、开采速度,保证矿区露天矿的生产安全。 In view of the open pit mining in Rujigou Mining Area, affected by the small kiln fire area, the temperature after drilling construction is too high and the blasting can not be carried out normally, which seriously delayed the production of open-pit mines; the high-temperature drilling and the toxic and hazardous gas-threatening workers in the fire area Life safety Special construction of integrated fire-fighting systems, the use of grouting, water injection, injection of three-phase foam and other comprehensive rapid management technology to improve the fire blasting, stripping, mining speed, to ensure the safety of open pit mine production.
