Geophysical exploration can be effective in detecting and monitoring potential sources of
coal mine water in-rushes and underground watercourses. Generally, in-mine seismic, DC …

The grout curtain in Zhangmatun iron mine, China, suffers from the leakage of water due to
the influence of multiple factors including inadequate grouting area, weak rock and mining …

Karst water in coal floors is the most common hazard in the coal fields of North China. Water
inrush disasters always occur due to reductions in the efficacy of a coal floor's water …

The mining of stratigraphically low coal seams in North China-type coalfields is subject to
water inrush from the underlying Ordovician limestone aquifer. The water-inrush coefficient …

The failure of waterproof coal pillars under the coupled effects of mining, excavation and
water seepage is a significant factor contributing to sudden water inflow accidents in …

Predictions of mining-induced water inrush accidents are challenged by data sparseness
and imbalances, as very few high-quality datasets can be obtained for successfully …

The water-richness of Quaternary unconsolidated aquifers is closely related to the safe
production of coal mining in shallow area near the Quaternary System. We attempt to …

Increase in downhole mining prompts the need to develop effective methods for
maintenance of shafts. Currently, grouting behind the shaft wall is the main approach used …

The problem of limestone karst water inrush from coal seam floors is becoming more and
more prominent, and gradually becoming the focus of water control work in coal mines …

The objective of this communication is to establish a new technique for GPR data
interpretation using continuous wavelet transform (CWT) approach. In the present study, we …
