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.

The introduction to this publication discusses the reliability of programmable control systems (PCS) and the need to be able to analyze the risks associated with these systems. Part 2 describes the general structure of the control & monitoring systems for PCS-controlled mine hoists, including the control component, safety devices & circuits, motor power stages, and PCS monitoring. Part 3 sets out the general principles to be applied to a PCS that controls or monitors a mine hoist in order to ensure safety. Optional requirements to improve reliability & maintenance of a PCS are also noted. The final part lists the proposed frequency of periodic tests & checks of the control & monitoring PCS used in the protection of the motor & electrical networks, temperature, brakes, limits of travel, wire rope, operation, safety circuit reset or interlock, and shaft sinking.

"The work draws on the author's nearly thirty years of teaching experience and abiding interest in mechanization of Indian coal mines. This book provides a good appreciation of mine hoisting technology, the importance of which to mine planners cannot be overemphasized. This book will prove useful as a reference work to practicing engineers and as a text book to undergraduate and post-graduate students of mining and mining mechanical engineering."--Back cover.

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.
