Abstract The sand bodies formed by braided fluvial fan deposits have a certain distinctiveness. They not only the characteristics of facies sandbodies but also follow distribution law alluvial bodies. variation that are present along and perpendicular to channel is relatively complex. Therefore, constraints in modeling process sand–mudstone this type reservoir essential. This study selects seco...

Deep rock bears dynamic loads such as machinery, blasting and disturbance in the mining process. The fracture mechanism of deep is a necessary prerequisite for engineering design analysis. To study under high situ stress, mudstone sandstone were selected research objects. mechanical properties energy dissipation assessed by using 50 mm diameter separated Hopkinson test device. According to simi...

Focusing on Xujiaweizi fault depression, the geological conditions and geochemical characteristics of deep natural gas formation in north Songliao basin are evaluated, resources estimated, favorable areas optimized. Shahezi Formation shale is a set coal bearing sediments with high organic matter abundance (TOC 1%～12%), over maturity (Ro 1%～4%) shore shallow lake facies, which mainly distributed...

Abstract Mudstone characterized by typical structures and mineral assemblages in the Tamusu pre-selected area, Inner Mongolia, Northwest China, has been selected as a potential host rock for China’s high-level radioactive waste (HLW) repository purpose. Based on indications of petrological geochemical characteristics, hydrothermal sedimentary geneses are well discussed from perspectives structu...

The influence of blasting energy on fragmentation and damage reserved rock is important for safety schedule drill-blasting construction in coal mine. This study aimed at investigating the dynamic mechanical properties mudstone mine using characterization method, their quantitative relation formula was also developed. impact compression experiments Huainan mining area were conducted to saturated...
