Research on the Prediction Method of 3D Surface Deformation in Filling Mining Based on InSAR‐IPIM
Energy Science &Engineering, EarlyView.Aiming at a series of defects existing in the monitoring of mining area by InSAR technology, this paper proposes an insar‐ipim model to predict the three‐dimensional surface deformation of filling mining. The parameters of the model are inversed by using the group optimization algorithm slime bacteria algorithm proposed in 2020, and the empirical ...

A review of volatiles in the Martian interior [PDF]
, 2016 Multiple observations from missions to Mars have revealed compelling evidence for a volatile-rich Martian crust. A leading theory contends that eruption of basaltic magmas was the ultimate mechanism of transfer of volatiles from the mantle toward the ...

Experimental Study on Instability Mechanism of Red Shale Roadway Under Dynamic Disturbance
Energy Science &Engineering, EarlyView.ABSTRACT To delve into the instability mechanism of the surrounding rock in red shale roadways, a bespoke device was chosen to fabricate a physical model, and a similar experiment was conducted with a blasting‐induced disturbance. A meticulous examination was performed on the evolution of surface fractures and the macroscopic failure patterns of the ...

Petrology of hydrothermal metasomatism of intra-ore dolerite dikes of mesothermal gold deposits
Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 There is a necessity of working up the geology-genetic theory of hydrothermal gold deposit formation instead of the four hypotheses excepting one another: granitogene, basaltogene, metamorphogene, polygene.

Energy Science &Engineering, EarlyView.ABSTRACT In the remining working face of thick coal seams, the instability of coal pillars near abandoned roadways can lead to advance fractures in the main roof, posing a significant threat to production safety. This study classifies roof collapse characteristics into four types and analyses the pillar instability mechanism using the Bieniawski ...
