Study on monitoring technology of the overlying strata spatial structures failure in shallow seam long wall face
In order to study the relationship between roof damage and roof pressure and investigate the forecasting techniques of roof pressure in shallow long wall face, this paper presented the use of micro seismic monitoring system on shallow depth overlying strata movement for three-dimensional motion condition monitoring. Through the analysis of micro seismic event location, this paper studied the extend of damage and structural layer of overburden in three-dimensional space, established the analysis of micro seismic monitoring on roof damage in shallow coal seam which based on the movement and structure of overburden space; studied the relationship between roof broken and strata behavior, analyzed the reason of slow advance on the accident of cutting the top and crushing the support, the research provided a new method for carrying out the study of formation mechanism and forecasting method of roof pressure in shallow long wall face.
