Abstract With the gradual increase in the average exploration depth of domestic coal industry,

the conflict between deep coal exploration technology and exploration requirements is

becoming increasingly prominent. A series of exploration disaster accidents caused by

geological disasters require a high level of survey technology before the deep coal exploration.

In this study, a high-resolution single hole measuring system for aquifers in coal seam is

proposed. The entire system can be divided into two parts: hardware and software. The

hardware probe integrates various sensors for different physical parameters using optical fibre

to communicate with the controlling part above the ground. The home-made software is then

used to receive and process the signals of temperature, pressure and orientation, as well as the

instantaneous image sequence of aquifer with flowing contaminants. A home-made novel

particle tracking velocimetry algorithm based on Voronoi diagram is used as the core algorithm

to analyse the image sequence and obtain the magnitude and direction of flow at the measuring

spot of aquifer. After practical tests, the system is confirmed to be able to effectively monitor

the hydrological conditions of the aquifer in coal seam. Therefore, the proposed algorithm can

be applied to the evaluation of hydrogeological conditions before well establishment for

coal-exploration and to the prevention of potential dangers during the exploration work.
