How to solve problems and promote the construction of green mines



1. Land resources and geological disaster prevention



The mining is strictly carried out in accordance with the design and is divided into steps from top to bottom. Dangerous rocks and pumice on the slope are cleaned up in a timely manner, and excessive slope angles are corrected to prevent geological disasters such as collapses and landslides< Br/>


Apply real-time monitoring technology during the mining process and establish a dynamic monitoring system< Br/>


During the stacking process of the temporary waste dump, timely slope cutting and foot pressing treatment should be carried out to prevent geological disasters from occurring< Br/>


2. Solid waste utilization



During the mining process of open-pit mines, ore loss is inevitable. The loss of ore refers to the loss of ore remaining in the mining site that has not been extracted or during the process of mining, transportation, and disposal. The principle of continuously improving the recovery rate and comprehensively reducing tailings should be followed, and block selection mining technology should be adopted< Br/>

Divide the width of the mining flat plate into several blocks, which meet the requirements of the equipment working space. The equipment mines the blocks in a horizontal layering method, one by one, and the next block is mined after each block is completed< Br/>


Collect the stone chips and powder generated from ore processing, classify, stack, and sell them for comprehensive utilization. Stone chips and powder can be used as desulfurization absorbents, raw materials for cement plants, etc< Br/>


3. Wastewater treatment



To solve the wastewater generated during the screening and washing process of mining processing, graded treatment can be adopted and a specialized wastewater treatment system can be constructed< Br/>


4 Dust control



The control of dust can be approached from two aspects: the overall prevention and control of dust pollution in quarries and the prevention and control of dust at dust source points< Br/>


Prevention and control of overall dust pollution in quarries:



Reduce dust pollution from the overall design plan by arranging development roads and chute locations, optimizing mining procedures< Br/>


Adopting energy-saving and environmentally friendly blasting technology, optimizing blasting technical parameters, and reducing blasting dust< Br/>

Dust source point dust prevention and control:



According to the characteristics and amount of dust raised at different dust source points, corresponding dust removal systems are equipped to control the dust< Br/>


5 Noise control



Apply advanced technology for vibration prevention, noise reduction, and sound insulation during equipment foundation installation; And strengthen the repair and maintenance of equipment< Br/>


Adopting multiple rows of hole extension
