辛置煤矿由于多年来不断挖潜与改造,矿井+540m水平和+450m水平资源已基本枯竭,以矿井目前的生产系统,接替水平+310m水平投产时,矿井通风线路较长,漏风率较大,通风负压远远超出《煤矿安全规程》的规定,给矿井的安全生产留下较大隐患。必须对矿井的通风系统进行改造,简化通风系统,使通风负压趋于合理,才能提高矿井的抗灾能力和安全程度,确保安全生产。对矿井当前南区通风系统进行了全面的阻力测定与网络解算模拟计算,分析了矿井的阻力分布状况,根据测试结果提出了调整方案及工程实施步骤,对煤矿下一步的安全生产具有重要的指导意义。
Due to continuous potential exploration and transformation over many years, Xinzhi Coal Mine has been basically depleted in the level of +540 m and +450 m. At the current production system of the mine, when the level of +310 m was taken over, the mine ventilation line was long and the air leakage rate was relatively large. Ventilation negative pressure far beyond the “coal mine safety regulations,” the provisions of the safety of the mine left a greater risk. It is necessary to reform the ventilation system of the mine to simplify the ventilation system and to make the negative pressure of the ventilation tend to be reasonable so as to improve mine disaster resistance and safety and ensure safety in production. Based on the test results, the adjustment scheme and project implementation steps are proposed, which are of great importance to the safety of coal mines in the next step Guiding significance.
