通过对庞庄煤矿张小楼井一条专用胶带输送机道和一个回采工作面建立局部反风系统的分析，论述了建立局部反风系统的必要性。根据煤矿井下生产实际，分析了在回采工作面和主胶带输送机道普及局部反风系统的可行性。并利用火风压理论，通过计算，得出了这两套局部反风系统的抗灾能力及其可靠性。建议在有关规定中明确规定，走向较长的回采工作面和运输任务较重的胶带输送机道在设计时必须考虑建立局部反风系统。 Through the analysis of building a local anti-wind system for a dedicated belt conveyor and a working face in Zhangzhuanglou, Pangzhuang Coal Mine, the necessity of establishing a local anti-wind system is discussed. According to the actual coal mine production, the feasibility of popularizing the local anti-wind system at the working face and the main belt conveyor is analyzed. By using the theory of fire pressure, the anti-disaster ability and reliability of these two sets of local anti-wind systems are obtained. It is suggested in the relevant provisions that the long-term mining face and the conveyor belt with heavier transport tasks should be designed with a view to establishing a local anti-wind system.
