随着矿井开采深度的增加,因地温升高而产生的矿井热害问题已日益凸显。济宁三号煤矿西翼采区的开采深度达到700 m以上,矿井热害主要出现在夏季,而冬季热害不明显,热害问题呈现季节性特征,说明地面气候对井下气候的影响显著。对矿井的热环境进行了动态自动监测,重点分析了地面气候对井下气候的影响规律和矿井热环境影响因素。
With the increase of mine exploitation depth, the problem of mine heat damage due to the increase of ground temperature has become increasingly prominent. The mining depth of the west wing of Jining No.3 coal mine reaches more than 700 m. The thermal damage in coal mines mainly occurs in summer, while the thermal damage in winter is not obvious. The thermal damage presents seasonal characteristics, indicating that the impact of ground climate on downhole climate is significant. The thermal environment of the mine was dynamically and automatically monitored. The influence of the surface climate on the downhole climate and the influencing factors of the mine thermal environment were analyzed emphatically.
