Exploration Stages
Exploration
Before mining construction stone, the quarry must be identified and explored. Exploration of quarries is carried out in two phasesof pee-jooyi and exploration.
A- P. Atmospheric reserves of construction stones
Operation P.Y. Yee is carried out in an area that may be tens or hundreds of square kilometers, with information about the field of intelligology, geomorphology, vegetation and the appropriate transport network that can be searched either by chance or using modern technology, including. Gis may be deployed to areas with potential for quarrying.
The principlesof the methods of building stone deposits are as follows (Nabiyan et al. 1991):
-
1- Using maps of the neologist and utilization of other available information, formations with stone units suitable for construction rocks are identified and these units are visited at different levels of the formation. D. J.
-
Take into account the conditions of extraction, the possibilities ofhand-watering and the creation of extractive chests. In the event that the stones are exceptional buildings with high prices, the conditions of problem extraction may also be cost-effective for the wateringofthe reserves.
-
3- The existence of large and healthy rocks abandoned on the hillside and the appearance color (e.g. whiteness of the mountain) is the first step. Those areas of M-set should be further investigated.
-
4- If a stone unit is suitable for construction stone in terms of general specifications, it should be visited from different parts of the area and blocks without ribbar materials and with topographic slope and suitable location and mineral should be selected for further investigation.
-
The mineral blocks or blocks in question should be visited by DaqQater, in addition to assessing the status of the YK Takton, the existence of seams and gaps, extraction conditions and facilities for the construction of extractive works chests and water-handed facilities.
-
6- A relatively large and portable piece of stone is selected and transported to the stone for the preparation of test plaques. The stone fragment is cut to investigate the appearance of stone at different sections of cutting, abrasion and resistance in different directions and considering the experience of the stone-cutting worker, it is examined.
-
If the preliminary studies confirm the suitability of the stone , the extraction of several cops experimentally, in consultation with a master of stone extraction and using mineral facilities with active mineral works and transporting the coupe to the stone, for experimental testing, preparation of plaques The standard, the study of the polishing surface of the stone in terms of beauty and marketing, can clarify the problems and problems of extracting and preparing the coupe, in addition, in this regard, the technical conditions of cutting and preparing the plaque are determined and all the necessary information is obtained by the MA. D. J.
-
Visiting an expert and experienced miner, from the mineral block to confirm the work and plan for the continuation of exploration operations, can be useful in preventing incomplete work and avoiding additional work and the case and basically doing the right thing.
B- Exploration of building stone deposits
Once the location of the quarry is identified, in order to determine the color and characteristics of the stone, the quality and amount of storage, the sample will be carried out, thus evaluating the economic capability of the extraction operations , if the economicality of the operation is proven, the ability to start the extraction operations after obtaining the necessary permits.
