A prototype-based rockburst types and risk prediction algorithm considering intra-class variance and inter-class distance of microseismic data

Frontiers in Earth Science
The prediction and classification of rockburst risk based on microseismic data is the premise of preventing rockbursts during deep mine excavation. By reviewing previous studies, this paper finds two problems that hinder the rockburst prediction: 1 ...

Experimental investigation into rock burst proneness of rock materials considering strain rate and size effect

Frontiers in Earth Science, 2023
In deep rock engineering, evaluating the likelihood of rock burst is imperative to ensure safety. This study proposes a new metric, the post-peak dissipated energy index, which accounts for strain rate and size effects in assessment of the rock burst ...

Supervised and unsupervised general framework for rockburst risk prediction based on feature contrast of long-term and short-term microseismic data

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
Short-term rockburst risk prediction based on microseismic (MS) data is a significant research task to overcome the rockburst challenge during the excavation stage. By reviewing previous short-term rockburst risk prediction methods based on MS data, this

Application of a Microseismic Method of Rock Burst Risk Assessment under Blasting Mining in Ashele Copper Mine

Shock and Vibration, 2022
Rock burst is a violent release of energy stored in the rock mass, which has been the focus of metal mine engineers. It gradually becomes a serious threat to both the mine’s workers and equipment.

Simulation study on the influence of different influencing factors on the amount of drilling cuttings

Meikuang Anquan
The drilling cuttings method is an important means to determine and predict the risk of coal and rock dynamic disasters such as rock burst. Accurately obtaining the variation law of drilling cuttings is one of the keys to understanding the stress state ...

Experimental Study of Prevention and Control of Rock Burst in Steeply Inclined Coal Seams by Mining Sequence and Filling

Shock and Vibration, 2022
The control and prevention of rock burst in a steeply inclined coal seam are essential. In order to figure out the effects of filling and mining sequence on rock burst in the steeply inclined coal seam, B3+6 and B1+2 coal seams in Wudong coal mine are ...

Rock Burst in the Kan'etsu Tunnel

Journal of the Japan Society of Engineering Geology, 1981
In excavation of the Kan'etsu tunnel, rock burst occurred expectedly. Especially for about 1 year since July 1980, many broken pieces of rock had sprung out frequently. Rock burst should be classified into sometypes, such as springing of rocks, cracks on face without springing of rocks, and only breakdown noises onface or in bed rock.
