摘 要:结合我国特厚及厚煤层的开采特征,对我国综放工作面巷道布置方式进行了总结,目前我国综放工作面巷道布置方式主要有在工作面布置2条巷道或多条巷道两大类,并分析了矿井地质条件、瓦斯赋存条件、采煤设备对巷道布置方式的影响。结合唐山煤矿综放工作面不同的巷道布置方式,详细指出了不同巷道布置方式对矿井不同条件的适应性。In combination with mining features of the ultra thick and thick seams in China, the paper summarized the gateway layout pattern of fully-mechanized top coal caving mining face in China.The present gateway layout patterns of fully-mechanized top coal caving mining face in China were mainly the two gateways layout of the coal mining face and the multi gateways layout of the coal mining face.The paper stated the mine geological condition,gas deposit condition and coal mining equipment affected to the gateway layout pattern.In combination with the different gateway layout patterns of the fully-mechanized top coal caving mining face in Tangshan Mine, the paper in detail ex- plained the suitability of the different gateway layout patterns to different mine conditions.
