Rope guidance of conveyances is commonly used in shafts of underground mines in numerous countries on almost every continent. This safe and economical way of guiding skips and cages does have one disadvantage, however, which is especially troublesome in the conditions present in the Polish mining industry. Rope-guided conveyances require additional support at mine levels, while shafts of Polish coal mines usually operate on many levels. Additional stiff guidance at mine levels used as a support negatively affects the effectiveness of rope-guided hoisting systems. The retractable guidance system was originally introduced at the 960 m level in the Leon IV shaft of the Rydułtowy coal mine in Rydułtowy (currently ROW mine, Rydułtowy department), Silesian voivodeship, Poland. This construction, consisting of moveable elements, similar to the typical stiff guidance used at mine levels, serves as a support for the conveyance whenever necessary. When it is retracted, it allows the cage to travel at full speed through the level, increasing the degree of effectiveness of the hoisting system of the Leon IV shaft. The retractable guidance system, the solution presented in this book, is a pioneering approach in the Polish mining industry. It has allowed improvement of the level of effectiveness of the Leon IV shaft of the Rydułtowy colliery. It is an innovative opportunity for rope guidance systems worldwide, as it solves their biggest problem in multi-level shafts.

Mining techniques have evolved over time, culminating in the well-defined field of “mining science,” which encompasses aspects such as engineering, chemistry, physics, technology, and management, among others. This book explains how mining techniques can be handled and improved further to make mining practices far more productive, safe, and eco-friendly. It is a useful resource for researchers, students, policy formulators, and decision-makers in different areas of mining and engineering.

This code of practice on safety and health in underground coalmines reflects the many changes in the industry and its workforce, as well as new developments in occupational safety and health policies and ILO instruments on occupational safety and health. A leaner, multi-skilled workforce, new technology and less prescriptive, more systems-oriented approach to addressing safety and health are also reflected in this code. The code sets out a national framework that specifies the roles of the competent authorities, employers, workers and their organizations. It also comprises a methodology for identifying hazards, preventing and minimizing risks, as well as specific provisions for safe underground coalmining operations.These specific provisions address most of the currently identified hazards and risks associated with underground coalmining. When used in conjunction with the code's methodology for hazard identification, risk assessment and control process, these provisions represent current best practice. As the same time, the code is drafted in a way not to inhibit the development of new technologies, better practice or the adoption of alternative measures that provide effective protection to all persons involved in underground coalmining.
