These examinations are based on an individual questionnaire and medicinal documentation of 8302 miners employed in 3-coal mines. In the previous parts an influence of occupational factors and socio-living conditions upon the occurrence of peptic ulcer in miners was presented. At present, on the ground of an analysis of 657 cases of peptic ulcer found among the examined population, considerable differences in the course of the disease in individual employed groups were found. In underground miners the cases with frequent recurrences were more frequent, compared with the staff employed on the surface. The amount of sick leaves caused by peptic ulcer was five times greater; the rate of absenteeism was the greatest. Recent cases (lasting no longer than 5 years), prevailed. Among the surface workers, as opposed to the under-round staff, almost all the cases of peptic ulcer called for hospital treatment. The percentage of chronic cases was much greater, the amount of complications and operations was twice as great. Sickness absenteeism caused both by peptic ulcer and other diseases was incresed. Hence it is evident that the work underground is too strenuous for those suffering from gastric ulcer and the miners with a heavy course of the disease most probably change the work i.e. they are transferred to the surface.
这些检查基于对3个煤矿8302名矿工的个人调查问卷和医疗记录。在前几部分中，介绍了职业因素和社会生活条件对矿工消化性溃疡发病的影响。目前，根据对受检人群中发现的657例消化性溃疡病例的分析，发现各就业群体中疾病进程存在显著差异。与地面工作人员相比，地下矿工中溃疡复发频繁的病例更为常见。消化性溃疡导致的病假天数高出五倍；旷工率最高。近期病例（病程不超过5年）占多数。与地下工作人员不同，地面工作人员中几乎所有消化性溃疡病例都需要住院治疗。慢性病病例的百分比更高，并发症和手术数量是地下工作人员的两倍。消化性溃疡和其他疾病导致的病假旷工率均有所增加。因此，很明显，地下工作对胃溃疡患者来说过于繁重，病情严重的矿工很可能会更换工作，即被调到地面。
