复杂环境下大采高超长工作面综采工艺实践与探讨

以神华宁夏煤业集团羊场湾煤矿为实例,介绍了大采高超长工作面(Y120202工作面)开采工艺、设备的配套选型、超长工作面矿压显现规律等。通过现场实践,总结了大采高超长工作面综采工艺的宝贵经验,这对于宁东矿区类似埋藏条件下采场管理有十分重要的指导意义和借鉴价值。

Practice and Discussion of Large Height and Super Longwall Fully-mechanized Mining in Complex Environment

Yang changwan Colliery of shenhua Ningxia Coal Industry Group for an example,this paper introduces large height and super longwall face(Y120202 face) mining,equipment selection and matching,strata-pressure behavior.Through the field practice,summarize valuable experi-ence about the fully-mechanized mining.It has important meaning and reference value for stope management similar to buried condition in Ningdong mining area.
