乡镇小煤窑由于受地理环境、投资经费来源、技术力量等因素的限制,在兴建或生产过程中.多为因陋就简,土法上马,手工操作,单眼独井,通风较差,以致一氧化碳中毒、瓦斯爆炸等安全卫生方面的问题时有发生。为了保护从业人员的健康,促进乡镇企业的顺利发展。我们对31家37孔小煤窑进行井下环境有关气体动态及从业人员生理值变化研究,结果如下:对象及方法(一)对象:选择开采时间5年以上,井下从业人员50人以上,无季节性停顿,人员相对稳定的小煤窑:选择22～45岁,3年 Due to the limitation of geographical environment, sources of funding and technical power, the township small coal mines are mostly constructed in the process of construction or production because of their simplicity, the introduction of native law, manual operation, single eye and poor ventilation, resulting in carbon monoxide poisoning and gas Explosions and other safety and health problems have occurred. In order to protect the health of employees and promote the smooth development of township enterprises. We conducted a study on gas dynamics of the underground environment and physiological changes of employees in 31 37-hole small coal mines. The results are as follows: Subjects and Methods (I) Subjects: We selected over 5 years of mining and more than 50 underground workers without any seasonal Stalled, staff is relatively stable small coal: choose 22 to 45 years old, 3 years
