This contribution reports an ichnological study of the well-exposed strata belonging to the Chefar El Ahmar Formation, located in the Saoura Valley (Ougarta Range, Northwestern Algerian Sahara). This unit consists mainly of irregularly alternating shale and limestone with some intercalated sandstone. The data reflect hemipelagic to pelagic carbonat...

Despite our understanding of the different mechanisms of man-made earthquakes, their short-term prediction and prevention is yet to be attained. In the present study, we propose an integrated four-step approach to predict and prevent man-made earthquakes or reduce their chance of occurrence. Our four-step approach includes locating the highly anoma...

Engineering disturbance-induced adjustment of the stress field in the surrounding rock is the main reason that leads to dynamic disasters in deep rocks. This study selected the mining roadway in the No. 92125 working face of the Chacheng Coal Mine as the engineering background for in-depth and systematical analysis on the principal stress path and ...

All across the world, and particularly in arid and semi-arid zones, the negative effects of agricultural productivity and unsustainable development have led to soil salinization, which is one of the critical environmental issues. Since the problem of salinization evolves at the scale of space and time, it is necessary to develop a comprehensive str...

The physical characteristics of the Earth’s surface play an important role in controlling the velocity of the wind erosion threshold. Therefore, to reduce the risks of dust storms, it is necessary to determine the impact of changes in this characteristic on wind erosion events in different regions. In this regard, this study was carried out to exam...

High-quality hydrocarbon source rocks are present in the upper Cretaceous layer in the western slope of the Songliao Basin. Oil and gas have accumulated in these rocks at the shallow edge of the basin, which has led to the formation of oil sand resources. This study uses the back-propagation (BP) neural network method to predict the distribution of...

The use of eggshell ash can lead to an increase in the strength of concrete. This study is aimed at investigating the high-strength sustainable performance of self-compacting concrete (HSSCC) through the usage of eggshell ash (EA) as a replacement for cement and reinforced with waste plastic (WP) fiber. Three different ratios of EA (10, 20, and 30%...

Fault core can act as a fine groundwater seepage conduit or barrier in coal mines in China. The material properties including the granularity and clay mineral content contribute to the complexity of the fault core’s hydrogeological characteristics, especially its permeability. Seven fault core samples in Renlou coal mine were collected for clay min...

The Miocene green clay from Zeramdine areas, of various physico-chemical, colour, and firing properties, have been widely used as raw materials in the fabrication of diverse building ceramic products. However, these clay resources are rapidly consumed which in turn affects the local industrial productivity. Up to now, only green clays are extracted...
