Attention to detailed geology and careful logging of drill core have been the hallmark of Geomapping's analysis of quarry potential. No quarry deposit is uniformly the same stone throughout. Zonation changes, stratigraphic variations, structural folding, and faulting are all common features in a stone deposit. Once these parameters are mapped and identified, the various stone types can be put to proper usage. These variations are sometimes misidentified or misunderstood so that the proper application of the stone becomes problematic. Too many times, if this attention to detail is not applied early on in the process of quarry development the problems, in turn, become apparent after the stone has been delivered to the customer or the job site and subsequent expensive corrective actions then need to be taken.

There are many new production methods available for quarrying. The stone characteristics, as well as, the logistics of each quarry site will dictate the suitability of a particular system. The use of torches, drills, wire saws, or chain saws is determined by the cutting and splitting characteristics of the stone. The spacing and pattern of fractures and joint systems are primary considerations in quarry design.

The handling systems that are selected are dependent on both the configuration of the deposit and the topography of the quarry site. In many instances, the derrick system is still the preferred method of moving quarry blocks. Most open pit type quarries, where the deposit is exposed at the ground surface over an extended area, utilize ramp roads and front end loaders or fork lifts for block handling and disposal of quarry waste rock.

Geomapping's experienced staff of professional geologists have the knowledge to determine the most cost effective quarry development and production system for your quarry site.

Shipping quarry blocks from Vermont to Italy for finishing, and selling Utah river boulders for colorful pavers west of the Mississippi are both good indications of the current demand for dimension stone. Making the most of a stone deposit is one of the keys to being profitable. Developing a local market for secondary quality stone and random block sizes often helps off-set the cost of quarrying. Knowing the percentage of a deposit that will yield top quality blocks suitable for making full sized slabs is a key element in preparing a realistic business plan for your quarry. This is one of the many areas in which Geomapping's geologists can apply their in-depth experience to your project.

The geology of the stone deposit, development & production methods, operating costs, transportation & handling, and market demand are all important design considerations which are incorporated into Geomapping's integrated approach to quarry planning.
