【摘要】 采区是煤矿生产最集中的区域,是瓦斯、煤尘及煤层自燃灾害的多发区。通风网路中的自然风压影响采区风流的稳定性,风流的不稳定诱发自然灾害的发生。论文导出了采区稳定性的判别式,并提出了具体的预防措施。所得结论对煤矿的安全生产有重要的意义。更多还原

【Abstract】 Mining areas are those of most intensive work in coal mining and those of disaster-prone from gas,coal dust,and seam spontaneous combustion.Natural wind pressure in ventilation network affects the stability of air flow at mining areas.The instability of air flow can provoke natural disasters.The discriminant of the stability of the air flow at mining areas was educed in this paper, and idiographic prevent measures were put forward.The conclusion is important to the safety of coal mining production.更多还原
