热害是严重威胁矿井安全生产的主要灾害之一,原岩温度的测定是矿井热害防治中最基础的工作。为了对城郊煤矿热害程度进行评价,文章采用热电偶浅孔快速测温法对城郊煤矿原岩温度进行了测试。根据测试结果对该矿原岩温度的分布情况进行了分析,得出矿井西翼受热水影响存在二级热害。测试结果可以为矿井进行热源分析、井下风流温度预测以及制定矿井降温措施提供重要依据。
Thermal damage is one of the major hazards that threaten mine safety production. The determination of primary rock temperature is the most basic work in the prevention and control of thermal damage in mines. In order to evaluate the extent of thermal damage in the coal mine in the suburbs, the article uses the thermocouple shallow hole rapid temperature measurement method to test the temperature of the original rock in the suburbs. According to the test results, the distribution of the raw rock temperature is analyzed. It is concluded that the secondary wing of the mine west wing is affected by the hot water. The test results can provide an important basis for the heat source analysis of the mine, the forecast of the temperature of the downwind airflow and the measures for cooling the mine shaft.
