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.

Dizhen xuebao利用美国喷气动力实验室（JPL）提供的全球电离层总电子含量（TEC）网格数据分析2018年5月28日吉林松原MS5.7地震空间电磁异常情况。通过算法对比确定滑动四分位法的优势，并利用该方法计算此次地震从震前14天至震后6天的电离层TEC异常变化的时间序列，结合空间环境和ΔTEC异常二维空间分布情况进一步分析，结果显示：① 极区磁亚爆强烈时段越靠近北部电离层扰动越强烈；② 震前TEC观测值先增大后减小，震后又回升，电离层异常幅度随着震中距的减小而增大；③ 电离层在空间分布上 ...

Deep Underground Science and Engineering, EarlyView.This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Procedia - Social and Behavioral Sciences, 2014 AbstractEarthquakes occur in the region where plate tectonic activity is still going on, and have killed more than one million people during the past 25 years. Earthquakes are natural hazards, which cannot be stopped but the hazards can be prevented from becoming disasters by taking appropriate preventive measures. The prevention such as re-building by

The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations
Deep Underground Science and Engineering, EarlyView.Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.
