霄云煤矿3煤层由于受古河流冲刷，井田范围内发育大面积的冲刷变薄区，变薄区对综采工作面的生产组织造成较大影响，也是煤质差的主要因素。该文结合1306工作面过变薄区的生产实践，总结出了“X”形进刀方式，在优化生产工艺的基础上最大限度地保证了煤质。
霄雲煤礦3煤層由于受古河流遲刷，井田範圍內髮育大麵積的遲刷變薄區，變薄區對綜採工作麵的生產組織造成較大影響，也是煤質差的主要因素。該文結閤1306工作麵過變薄區的生產實踐，總結齣瞭“X”形進刀方式，在優化生產工藝的基礎上最大限度地保證瞭煤質。

Due to erosion by ancient rivers in Xiaoyun 3 coal seam, occur a large area of scour thinning zone within the scope of mine, the thin area has a greater impact on fully mechanized working face production organization, but also is the main factors that cause the poor coal quality . Combining the production practice of 1306 working face in the thin area , summed up the "X" shape feed mode, which maximally guarantee the quality based on the optimization process.
