Report hits the ground and mine: Building stone quarry Samen Hujaj

Mhmdhamd sun

Samen mine located on the outskirts Bajestan Hujaj located at 50 kilometers from the city of Gonabad. The mine exploration work was carried out in 1993.

The quarry of marble (calcium carbonate) extract.

Physical characteristics:

1.       Density of 2.7 grams per cubic centimeter

2.       Compressive strength of 675 grams per square centimeter

3.       Clay content below 2%

The clay annoying element in this stone for stone processing and construction Sakhtmanyst and great ideal.

It was an inverse extraction step is to extract the best slope is 30 to 40 budget

Extraction:

Preparation, drilling, cutting, block up, shape up, the quality, grading and transportation for factory

Is processed.

Shipping is based on the principle of cutting and drilling. Conventional methods for cutting with diamond wire is in Iran, which is quite economical and efficient and is effective on most stone. Drilling, and started down the size of the blocks is given to the person digger. That was all then from top to bottom by measurement instruments, measurements were made and the holes to be. Holes that are connected from the top and through K pipes and wires rejected his cut longitudinally from top to bottom is the standard of 6 to 7 meters height stone. The remarkable thing is not that quick turnover diamond wire stone, but he soon recede speed device Cutting that affects the cutting speed.

Cretaceous limestones, tectonic structure of typical and bottom make this area a stone column Iran.

Between 1998 and 2008, 20 mines were active in the area. Exports to South East Asia region, the area of ​​the Persian Gulf country that has been suspended due to political and high costs. Major exports to Mahmoud Abad Isfahan, Mashhad and Tehran Shamsabad done.

Grading factors:

Color stability, health, six on cutting and cut to fit.

Stones are divided into the mine to 6 degrees with a stone plaque formation has a direct relationship For example, a grade 1 per

tonne 10 meter high stone plaque that at best 40% of the ore grade 1, 2 and 3 there.
