为了解煤矿井下作业对井下矿工高血压发病的影响 ,采取整群随机抽样 ,对地面作业和井下作业 (-2 5 0m～ -4 5 0m)的矿工进行问卷调查和血压、心率、身高、体质量的测量 ,经统计学处理 ,分析矿工高血压发病的原因。结果青壮年 (年龄≤ 40岁 )矿工中 ,井下作业组高血压检出率明显高于地面作业组 (P <0 0 5 ) ,且井下工龄越长 ,高血压检出率越高 ,矿工平均动脉血压 (ABP)与井下累计作业时间呈正相关 (P <0 0 5 )。
In order to understand the effect of coal mine operation on the incidence of hypertension in underground miners, a random sampling cluster was adopted to survey the miners in ground operations and downhole operations (-250 ~ 450 m) and the relationship between blood pressure, heart rate, height, body The quality of measurement, the statistical analysis, analysis of the causes of miner hypertension. Results Among the miners (≤ 40 years old), the detection rate of hypertension in the downhole operation group was significantly higher than that in the ground operation group (P <0.05). The longer the downhole service length and the higher the detection rate of hypertension, the average Arterial blood pressure (ABP) was positively correlated with cumulative downtime (P <0.05).
