Run-of-quarry

Primary crushers [5.3] need to be capable of handling run-of-quarry rock, which may have lump sizes of up to 1 or even 2 m. The fine fraction produced by the primary crusher is generally removed by screening as it falls within the saleable size range. 

Storage of run-of quarry and partially processed limestone is necessary to provide surge capacity between the various processing stages. Storage of fully processed limestone is also required to service despatches, to provide a strategic reserve and to store surplus grades. 

Run-of-quarry (ROQ) describes the material produced by quarrying activities for subsequent processing. It includes fines, clay and other impurities, but not material sent directly to tip. 

The fifth example study has shown that using sand encapsulated in geotextile containers for the core of rubble mound breakwaters, which is about one order of magnitude less permeable than a conventional core made of quarry run, may provide many advantages. This is particularly the case when rock material (quarry run) is... 

The advantages of the nonconventional geocore concept are expected to be particularly revealed when applied to a seawall protecting reclaimed land (Fig. 12.17(d)), due to the difficulties to protect the latter from being washed out through a conventional core made of quarry run.

Locality no. 3 of Osztramos is situated in the southern corner of section XI of the quarry, at 340 m a.s.l. The red clay sediment deposited in a cave formed by a cleft running in a northwest to southeast direction was blasted in 1971 (Picture 7). At the time of palaeontological collections, in 1969 and 1970, the upper part of the profile, 10 m high and 5-6 m wide, was made up of yellowish sediment closed downwards by a calcite shelf, below which reddish brown sediment was found. The material was collected from 9, arbitrarily delimited (20-30 cm wide) strata. Analysis by layers has not been carried out so far (the aim of such study would be to detect differences between the layers). According to Janossy (1969b, 1970), the following faunal list is known, mainly from layers 2 and 3. 

The similarly aged locality no. 7 of Villany is situated at the southwestern corner of the same quarry, and comprises a small cleft running in a north to south direction...

Safety devices have to be provided to prevent vehicles that run on rails from running away. No ropeway shall be used unless it meets the requirements of the Quarries (Ropeways and Vehicles) Regulations 1958.
