通过结合淮北矿业集团有限公司朱仙庄矿 84 13- 2工作面的综放开采实践 ,利用深基点跟踪观测法 ,探讨了“三软”中厚煤层在予采顶分层情形下综放开采时顶煤变形运移特性 ,对类似地质条件的“三软”工作面采用综放开采技术时确定合理的工作面生产工艺参数提供了依据
Based on the fully mechanized top coal caving mining practice of 8413-2 working face of Zhu Xianzhuang Mine of Huaibei Mining Group Co., Ltd., the deep base point follow-up observation method was used to explore the top of fully mechanized top coal caving mining under the condition of pre-mining top strata, Coal deformation and migration characteristics of similar geological conditions of the “three soft” working face using fully mechanized caving mining technology to determine the reasonable parameters of the production process provides the basis
