随着矿井开拓不断加深,我国某些矿山井下温度超过安全规程。320矿床水大温高,在国内含热水矿山中实为首屈一指。自一九五八年揭露10号坑道硅质带热水(水量83米~3/时,水温43℃)以来,随着开拓工程的加深,目前主矿带80米中段巷道已揭露53℃热水。热水涌出是井下高温的根本原因。工作面一般气温为30—38℃,个别超过40℃,致使作业条件恶化。因此研究地温场的特征,对查明矿床热水分布规律,探讨经济合理的降温措施有一定意义。 矿区位子新华夏沉降带中、永桂复式向斜东南翼
With the deepening of mine development, some of our mines downhole temperature exceeds safety regulations. 320 deposits of water temperature is high, in hot water mines in the country is second to none. Since the tunnel No. 10 was unveiled in 1958, with the thermal water of 83m 3 / h and the water temperature of 43 ℃, with the deepening of the pioneering work, the middle part of the 80-meter main tunnel has exposed 53 ℃ of heat water. Hot water is the root cause of high temperature underground. General face temperature of 30-38 ℃, individually over 40 ℃, resulting in deterioration of operating conditions. Therefore, the study of the characteristics of geothermal field is of some significance to ascertain the law of distribution of hot water in the deposit and to explore economically and economically cool measures.
