孟加拉国巴拉普库利亚煤矿地热特点为:地温梯度大、原始岩温高、涌水量大且水温高,并且煤层地温和水温及增温率明显高于顶底板,典型的地热与热水混合型热害矿井。热害给孟巴矿的建设和生产带来了极大的影响。根据多年观测和治理实践,对孟巴矿复杂的地热特点进行了分析,对该矿热害的成因进行了探索和分析,同时介绍了多年的治理措施和效果,可为类似矿井的高温热害防治提供借鉴。
The geothermal characteristics of the Balapukulia coal mine in Bangladesh are as follows: the geothermal gradient is high, the original rock temperature is high, the water inflow is large and the water temperature is high, and the geothermal water temperature and the rate of temperature increase are obviously higher than those of the top and bottom plates. Typical geothermal and hot water Mixed thermal mine. Thermal damage to the Mombasa mine construction and production has brought tremendous impact. According to the multi-year observation and management practice, the complex geothermal characteristics of Mengba Mine are analyzed, and the cause of heat damage is explored and analyzed. Meanwhile, many years of governance measures and effects are introduced, Prevention and control to provide reference.
