The article presents the possibilities of using inclined boreholes. Three cases were considered: backfill boreholes, hydrogeological boreholes, and borehole heat exchangers. The advantages and disadvantages of these solutions are described. In the case of an inclined backfill borehole, the time required for backfill material injection is minimized. In the case of an inclined hydrogeological borehole, the active filter area is increased, improving efficiency. In the case of inclined borehole heat exchangers, the unit power exchange with the rock mass is increased by increasing the length of the borehole in the layer with the best thermal conductivity.

The latest environmental trends involve the use of renewable energy sources, reducing carbon footprints and minimizing the effects of past human activity. It is therefore very important to minimize the effects of the exploitation of useful minerals by eliminating mining landslides and rock voids. One of the ways to protect them is through drilling works by drilling backfill holes. The authors of the present study show the possibility of adapting diagonal drillings to drill backfill boreholes. It helps to connect voids, caverns or cavities by backfill boreholes through the injection of backfill material into them. The time of pumping the backfill material in the case of vertical and diagonal holes are analyzed.

One approach to enabling construction, engineering, and mining activities in subsoil with insufficient geo-mechanical properties is to employ innovative methods and technologies. These can effectively modify the physical and mechanical characteristics of the subsoil. The article explores engineering techniques that can enhance the geotechnical properties of soils in locations where they exhibit dysfunctions, such as reduced stability and bearing capacity. Additionally, the paper emphasizes the importance of conducting specific geo-engineering tests to accurately assess the geotechnical conditions. The research directly evaluates the stability of a railway section within the Western Carpathians and presents findings from both field and laboratory tests. Given the instability observed in this section, there is a pressing need for geo-engineering reinforcement measures. These efforts aim to enhance the geotechnical properties and safeguard the railway embankment from potential landslides. Detailed accounts of these remedial works will be the focus of a subsequent study.

Knowing the impact of technical solutions on the drilling process is a very important element in the process of the exploration of new fossil fuel deposits. Drilling equipment used during drilling operations is highly liable to all conditions which prevail in the well bore. The study of the impact of drilling fluid flow with various rheological properties on the strength and work of drill stem components will allow to search for the best solutions. The article describes the design and construction of two boreholes, fill up with 9 5/8" (244.5 mm) and 24" (609.6 mm) casings. The designed boreholes will be a joint part of the drilling laboratory in the S-1 building at AGH-UST in Krakow. Research The research described above can be done in openholes and implemented at the beginning of the design process for drilling works in new deposits. In addition, it will provide an opportunity for all engineers to get to know the behavior of components operating in an open hole.
