某铀矿井下作业中段热源分析与降温措施研究

Study on Heat Source Analysis and Cooling Measures in a Uranium Mine

对某铀矿井下作业中段的热源进行了分析,计算了矿井中各部分热源的散热量,得出了地下涌水、空压机、无轨设备、岩壁对井下空气温度升高的贡献率分别为53.78%、26.04%、13.28%和6.90%。根据调查结果,从调整风路、加大风量快速形成岩层调热圈、管道排放地下涌水等方面进行研究,提出了降低矿井-150 m中段南部作业面温度的综合措施,使-150 m中段采掘面温度控制在28℃以下,保障了矿井内的安全生产及员工生命健康。

The heat source of a uranium mine was analyzed.The heat contribution of each heat source in the mine is calculated.The results show that the contribution rates of underground water gushing,air compressor,trackless equipment and palisades to the rise of underground air temperature are 53.78%,26.04%,13.28%and 6.90%respectively.Research has been carried out from the aspects of adjusting the air path,increasing the air volume to quickly form a rock heat regulation circle,and isolating the discharge of underground hot water by tube,and put forward comprehensive measures to reduce the temperature of the southern working surface of the-150 m middle section of the mine.These measures have controlled the temperature of the mining face in the middle section of-150 m to below 28℃,and ensuring safe production in the mine and the lives and health of employees.
