石圪台煤矿71203综采工作面过大断层技术研究与应用

Development and application of the technology for Shigetai Mine's longwall face #71203 to trasverse large fault

以石圪台煤矿71203工作面在复杂地质条件下过落差大于6.5m的断层为典型实例,从过断层的方案、工艺及采取的特殊措施等方面入手,总结出了综采工作面过断层的关键技术。

This paper focuses on the typical case how Shigetai mine s #71203 longwall face traverses faults with throws larger than 6.5m under complicated geological conditions. Concentrating on a description of a technical scheme for the face to pass through the faults,the necessary techniques needed and special precautions taken,this paper induces the key technical solutions to the traverse of longwall faces through faults.
