Efficiency optimization of plow systems through the precise planning of new
and comprehensive enhancement of operating longwalls
TPlow technology reemerged and increased in importance in recent years, as many operators worldwide searched for
an effective technology for extraction of thin and medium thickness coal seams. Plow systems were significantly impro-
ved in recent years. This resulted in higher production from plow faces. Nevertheless, there is an appreciable potential
for further performance increase by the means of optimal technical, procedural and organizational improvements. Very
important for the achieving of planned production rates is a correct design of plow faces. On the other hand, in many
cases a performance improvement is possible without significant changes of the longwall system, simply requiring con-
sistent analysis and effective realization of conclusions. The main message of this paper is: production can be strongly
increased, even doubled, by paying careful attention to the correct design and optimal operation of a plow face.

Plough longwall operations under challenging geological conditions
In German coal mining, comprehensive experience is available in the grading of geological faults. The available expe-
rience has produced a level of expertise which enables the maintenance of high production figures even under difficult
conditions. This is demonstrated by the many successful projects of RAG. The paper describes in the following several
successful case examples and illustrates that the collected know-how can be used globally, even for future challenges,
by German RAG Mining Solutions GmbH to successfully operate modern high-performance plough companies under
difficult conditions.
