深井矿井热害治理技术

Treatment Technology for Heat Damage in Deep Mine

为解决矿井开采深度的增加和采掘机械化水平的提高造成深井矿井热害日益严重的难题,大强矿采取了增加风量、避开局部热源、预冷进风风流、隔绝高温围岩、采取个体防护和机械制冷降温相结合的综合矿井热害治理技术解决了热害严重影响矿井安全生产、高效生产的难题,同时也保证了职工的身心健康。通过大强矿深部矿井热害治理过程,摸索出了成熟的深井矿井热害治理技术。

To solve the problem of thermal damage caused by the increasing of coal mining depth and mining mechanization level,Daqing Coal Mine uses integrated mine thermal damage treatment technique, including increasing air volume, avoiding local heat source, pre-cooling intake airflow, isolating from high temperature surrounding rock, adopting individual protection and mechanical refrigeration, to solve the problem that thermal damage seriously affects mine safety and efficient production, and to ensure the staff＇s physical and mental health at the same time. Through the thermal damage treatment of deep shaft in Daqiang Coal Mine,we fish out mature deep mine thermal damage treatment technology.
