Automatic Classification of Microseismic Records in Underground Mining: A Deep Learning Approach
IEEE Access, 2020 The identification of suspicious microseismic events is the first crucial step in processing microseismic data. In this paper, we present an automatic classification method based on a deep learning approach for classifying microseismic records in ...

Multi-parameter monitoring of a solution mining cavity collapse : first insight of precursors [PDF]
, 2011 International audienceIn order to improve our understanding of the large-scale ground failure phenomena caused by old underground mining works, a solution mine was instrumented in 2004 prior to its collapse as part of the mining scheme.

Resonance in downhole microseismic data and its removal [PDF]
SEG Technical Program Expanded Abstracts 2016, 2016 Author(s): Zhang, Z; Rector, JW; Nava, MJ | Abstract: We identified resonance due to poor geophone-borehole cou- pling in downhole microseismic data and proposed to use spik- ing deconvolution and relative spectrum analysis to remove its effect. The resonance may hinder the arrival time picking and contaminate microseismic waveform spectrum.

Energy Science &Engineering, EarlyView.With the advancement of coal mining technology driving the development of working faces toward increased mining heights and extended lengths, the enlargement of face dimensions has led to expanded overlying strata failure zones and intensified ground pressure manifestations. Consequently, traditional methods for determining hydraulic support resistance
