随着煤矿生产的发展,矿井不断延深,地热研究就日趋重要。陶庄煤矿垂直深度500～600米的250采区工作面温度高达29～30℃,超出了煤矿保安规程规定的上限(26℃)。几年来,该矿先后在十四个不同性质的钻孔内测了地温。最大测温深度达900米。该矿测量地温曾先后采用过水银温度计、DZW-11型井温仪及中国科学院地质研究所研制的半导体测温仪。长期观测表明,该矿常温层深度在30米上下,常温层之上,曲线随季节而
With the development of coal production, the mine continues to deepen, geothermal research is increasingly important. Taozhuang coal mine vertical depth of 500 to 600 meters 250 mining face temperature as high as 29 ~ 30 ℃, exceeding the upper limit of coal mine safety regulations (26 ℃). In the past few years, the mine has measured the ground temperature in fourteen boreholes of different nature. The maximum temperature depth of 900 meters. The mine ground temperature measurement has been used mercury thermometer, DZW-11-type well temperature instrument and Institute of Geology, Chinese Academy of Sciences developed a semiconductor thermometer. Long-term observations show that the depth of the normal temperature of the mine is about 30 meters above and below the normal temperature, and the curve varies with the seasons
