A comparative experiment of telluric field frequency selection method and audio-magnetotelluric method next a water well

The telluric field frequency selection method (TFFSM) has been proposed for more than 40 years and has achieved good exploration results in groundwater exploration. The cause of its anomaly formation has always been one of the issues that people are concerned about. This article...

Characteristics of horizontal flame spread and merging of discrete fuel arrays with dual fire sources: Effect of array distribution and layout

Discrete fuel arrays in forest and built environments pose significant hazards during multiple fire source combustion. This study quantitatively investigates the influence of array distribution, through a systematic combination of eight array spacings ( S = 2–9 mm, stepped by 1 m...

Multidimensional Analysis of Ore Spontaneous Combustion Tendency Based on IAHP and Improved Interval Approximation

To conduct a scientific and comprehensive analysis of the spontaneous combustion tendency of sulfide ores and improve the safety production level of sulfur mines, an indicator system for determining the spontaneous combustion tendency of sulfide ores and a comprehensive classific...

Deformation Detection and Structural Failure Mechanism of Large Mine Chutes: A Three-Chute Case Study at an Iron Mine

To examine the deformation behavior and failure mechanisms of large-scale mine chutes under complex service conditions, we performed multiple C-ALS three-dimensional laser scanning surveys on the 1#, 2# and 3# chutes at an iron mine in Anhui Province. The results showed that all...
