Critical expansion points: Mechanical signs of surrounding rock instability
Deep Underground Science and Engineering, EarlyView.This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...

Dizhen xuebao本文将基于压缩感知理论的地震观测数据重建方法用于天然远震事件的P波到时处理之中，基于曲波（curvelet）变换，建立基于L1范数的正则化反演模型，并采用迭代收缩阈值算法（ISTA）求解该模型。针对在内蒙古布设的流动地震台阵记录到的远震波形数据，对其进行稀疏采样，采用稀疏反演重建方法对欠采样数据进行重建，并拾取重建数据的P波到时，之后开展远震P波层析成像进行验证。研究结果表明，远震天然地震观测数据在曲波变换中表现出稀疏性，可利用压缩感知方法实现远震P波数据的完备化处理 ...

An optimizing microseismic method for rock burst early warning based on mining production process
Deep Underground Science and Engineering, EarlyView.A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

Evaluating the Economic Response to Japan's Earthquake [PDF]
This paper compares the 1995 Kobe earthquake with the more recent one in Tohoku. The impact of the recent earthquake on industrial production was much larger and long-lasting than that of the 1995 earthquake.
