Abstract
In view of the complex geological conditions,multiple fault structures,and poor integrity of surrounding rocks in the mining working face of Liuzhuang Coal Mine,which are prone to coal wall spalling,roof advanced extraction and caving,support instability,difficulty in protecting the side and roof,and support tilting during the mining process,combined with advanced experience in surrounding mines,a pre grouting governance technology for faults in the coal mining working face is proposed,by adopting mining schemes and control measures such as"static governance first,dynamic governance cooperation,and smooth progress of the working face",the difficult problems during the period when the working face passes through fault structure zones are solved,providing technical support for the safe production of the coal mining working face.关键词
