调查某煤矿井下男性凿岩风钻工165名、电钻工108名.同时选择该矿不接触振动的井下男性杂工100名为对照组。风钻组钻机计权加速度为17.7—25.5m/S~2,电钻组钻机计权加速度为4.6—7.0m/S~2。
Survey of a coal mine underground drilling rock drill male 165, electric drill 108. At the same time select the mine does not touch the vibration of the underground male handyman 100 as the control group. The weighted acceleration of the drilling rig group is 17.7-25.5m / S ~ 2, and the weighted acceleration of drilling rig group is 4.6-7.0m / S ~ 2.
