摘　　要：以西河煤业3#复采煤层作为研究对象,对其复采煤层规模和服务年限进行了分析,提出了复采开拓方案,并进一步分析了复采采区布置、井下运输和矿井通风等内容,针对该复采煤层特征,采用放顶煤采煤工艺,煤层厚度大于3.0 m时放煤,煤层厚度小于3.0 m时禁止放煤。该研究可以为西河煤业3#复采煤层的开拓布置提供一定的技术依据。The studied object was the 3#repeated mining in Xihe mine.The scale and service life of the repeated mining coal seam are analyzed.The development scheme was putted forward.The layout of mining area,underground transportation and mine ventilation are further analyzed.According to the characteristics of the repeated mining seam,the caving coal mining technology was adopted.The caving is admitted when the thickness of coal seam is greater than 3 m and when the thickness is less than 3 m the caving is prohibited.The result can provide certain technical assistance for the development scheme of 3#repeated mining.
