The Danger Of Stone Mining


Although the recent mine safety accidents have nothing to do with the stone industry, as a part of the mining industry, we obviously can not completely stay out of the trouble. Only by carefully drawing lessons from the accident, drawing inferences from one instance, and taking effective measures can similar accidents be avoided.

01. Man-made hazards

Generally speaking, the main daily operation activities of granite mines include rock drilling, blasting, trench excavation, mining sawing, shovel loading, cleaning, transportation, power supply and distribution, waterproof and drainage, dumping, and equipment maintenance. These activities require the participation of a large number of operators, which inevitably leads to some potential human hazards.

Generally speaking, the potential human hazards in the daily activities of granite mines include psychological, physiological, behavioral, and technical aspects.

Psychological and physiological safety mainly refers to the safety awareness and physical state of operators. After all, in the process of the mine operation, it is inevitable that due to long-time and heavy-duty operation, the physical condition of operators in a certain period does not meet the actual operation needs, or leads to the decline of perception and identification ability, or leads to mood, risk-taking, fluke, laziness, paralysis, carelessness, and other psychological problems, and then makes some problems, such as failing to check three inspections in one shot and three inspections in blasting operation Unsafe behaviors such as fatigue operation of equipment and fatigue driving lead to accidents.

Behavior safety mainly refers to some subjective negligence of operators, such as illegal command, illegal operation, etc. At present, mining enterprises generally attach importance to the training of operators. However, due to psychological and physiological factors or lack of understanding of necessary technical knowledge, some operators may still have management defects in the process of management, such as illegal operation in the process of an explosive collection, transportation, charging and operation, random handling of misfire and high-altitude taboo operation, There are many problems, such as illegal people standing around the equipment, wrong power transmission, not timely maintenance of the equipment, etc.

Business technology mainly refers to some subjective behavior faults of operators, such as ignorance or inadequate understanding of operation procedures, safety protection measures, safety system, management measures, and technical measures, which lead to accidents in the operation process, such as not using safety helmet, safety belt, earplug, etc Personal protective measures such as masks, illegal operation of machinery, over the excavation of slope toe, operation not following design requirements, overloading, etc.

02. Equipment hazards

Equipment hazards mainly include mechanical equipment, production facilities, safety facilities, dangerous chemicals, personal protective facilities, occupational hazards, and moving objects that must be used in the process of granite mining and production. Mechanical equipment mainly refers to rock drills, down the hole drills, circular saws, diamond beaded saws, rock jacking machines, excavators, forklifts, loaders, air compressors, etc. such equipment may cause mechanical injury, electric shock, fire explosion, and other accidents due to the type selection failing to meet the operation requirements or structural defects of its design, long-term use damage, inadequate maintenance, and other reasons.

Production facilities mainly include working platforms, safety platforms, cleaning platforms and other kinds of steps, slopes, road transportation facilities, power supply and distribution facilities, waterproof and drainage facilities, blasting facilities. Because of the unreasonable parameter design, such facilities may produce some major hidden dangers such as slope collapse, which may lead to landslides, collapses, falls from high places, and other accidents, In addition, due to inadequate maintenance, mining, transportation, drainage, and other operations may be blocked, and even lead to electric shock and fire.

Safety facilities mainly include protective fence and retaining wall to protect road transportation safety, protective fence to protect power supply and distribution safety, lightning protection grounding, screen protection device, interlocking device, fire extinguisher, fire hydrant, and other fire-fighting equipment used in fire-prone places and equipment, road transportation reflector and safety signs in dangerous places. The damage and damage of this equipment may lead to high-altitude falls, traffic accidents, fire, and other accidents.

Hazardous chemicals mainly include inflammable oil substances used in blasting operations and various mining and production machines. These chemicals are often flammable. Improper management and use may cause fire, explosion, and harmful gas emissions. Personal protective facilities include a safety helmet, safety belt, anti-skid shoes, gloves, earplugs, and dust masks. It is possible to cause accidents if the protective facilities are not worn during the operation, the quality of the protective facilities is not up to the requirements, and the protective facilities are not worn correctly.

Occupational hazards mainly include dust, noise, vibration, and toxic gases produced in the process of rock drilling, sawing, drilling, and stone transportation in granite mines. These harmful elements may lead to occupational diseases such as pneumoconiosis, noise deafness, and poisoning asphyxia. Moving objects mainly refer to flying rocks and collapse bodies produced in the process of rock drilling, blasting, shovel loading, and cleaning. These moving objects can cause unnecessary accidents such as object strike.

03. Environmental hazards

Environmental hazards are mainly concentrated in geological environments, natural environments, and working environments.

Among them, geo-environmental hazards mainly include geological structure and hydrogeology. Reflected in the granite mine, it mainly includes the soft and weathered overburden, the development of ore body fissures, bedrock fissure phreatic water, and so on. The main hazard sources of the natural environment are rainstorms, heavy snow, earthquake, hail, lightning, etc. these factors may lead to landslides, collapse, debris flow, and other accidents, resulting in a large number of casualties and property losses.

The hazard source industry of working environment includes working space environment, lighting, smoke, and so on. In some cases, the working space is too narrow, the working face is uneven, the transportation road is rough, the foundation is soft, the lighting is insufficient, the slope is too large last night, the site is wet and slippery, the smoke is diffuse, etc., which may affect the actual mine operation efficiency, and then increase the possibility of safety accidents.

04. Management of hazards

The management of hazard sources is closely related to the safety awareness of mining enterprises, mainly including six aspects: safety organization, safety training, and education, safety production responsibility system, safety technical measures, safety inspection, and emergency management.

Generally speaking, mining enterprises should set up corresponding safety production committees and safety management departments according to local requirements, standard requirements, and actual needs, set up safety production leading groups and safety management departments in production outsourcing units, and equip corresponding leaders in charge of safety production, department safety directors, safety engineers, and safety staff, Establish and improve the safety production responsibility system of all functional departments and all employees, formulate the operation procedures of all links and the safety technical operation procedures of all types of work, conduct relevant safety training for the main responsible persons, safety management personnel, special operation personnel, and other employees, and urge the personnel at all levels of the company to strictly fulfill the requirements of the safety production responsibility system and work with certificates.

At the same time, the person in charge of safety shall carry out daily inspections, special inspections, and comprehensive inspections on the mine regularly or irregularly, and timely rectify the problems found. In addition, enterprises must have a complete and practical emergency plan and carry out emergency drills in strict accordance with the requirements. The fault of any of the above links may lead to the occurrence of mine safety production accidents.

Safety is the first factor of production, and behavior must be completed under the premise of ensuring safety. OK, let’s write about the danger of mining for the time being. I look forward to your email at
