特深矿井通风系统降阻技术分析与优化

Analysis and Optimization on Resistance Reduction Technology of Mine Ventilation System in Ultra Deep Mine

随着新汶矿区孙村煤矿开采深度的不断增加,地压大、地温高、生产系统复杂、通风阻力大、地质构造复杂等一系列难题,成了制约矿井安全生产和可持续发展的瓶颈。针对这些难题,通过特深矿井优化通风系统降阻技术,简化了通风系统,降低了通风阻力,改善了生产作业环境,提高了采区生产能力,为深部矿井复杂条件下安全生产和可持续发展奠定了基础。

With the mining depth continually increased in Suncun Mine of Xinwen Mining Area,the problems of the high ground pressure,high thermal temperature,complicated production system,high ventilation resistance,complicated geological structures and others became the ＂bottleneck＂ to restrict the mine safety production and sustainable development.According to those problems,with the resistance reduction technology applied to optimize the mine ventilation system in the ultra deep mine,the ventilation system was simplified,the mine ventilation resistance was reduced,the mine production operation environment was improved and the production capacity of the mining block was increased,which could set up the basis to the mine safety production and sustainable development in the ultra deep mine under the complicated mine conditions.
