地下采矿的特点是在比较狭窄的地方(矿坑,独立工作而)集中作业,于是在这些地方集中很多产生高噪声级与高振动级的机器和机械。目前与采矿业的噪声作斗争的主要方向是:在机器和机械上设置消声器;采用吸声材料制成的保护装置;工作地点的噪声级在
Underground mining is characterized by a concentration of work in relatively narrow places (mines, working independently), where many machines and machines producing high noise levels and high vibration levels are concentrated. The main areas of the current fight against mining noise are: silencers on machines and machinery; protection devices made of sound-absorbing materials; noise levels at workplaces
