Mine Hazard Analysis And Safety Managemen Research

Recently mining accidents occur frequently in our country,with very serious consequences.Scientific and rational mine production is the most important way to avoid or reduce mine accidents.In this paper,Shaqu mining Shaqu Coal Mine 4#5#seam,for example,dangerous and harmful factors mine were to identify and analyze,gas and coal dust in the process of coal mining is a major hazard,coal mining process ventilation facilities are set incorrectly,the management is not in place,may produce gas overrun,causing the gas explosion and other accidents;coal mining process is often accompanied by a large number of coal dust generation,resulting in the occurrence of coal dust explosion.In addition,the process of coal mining,coal mining face first to the pressure,cycle pressure,roof,etc.Face across the period of the geological formation is a major hazard,should strengthen the prevention and management.Coal spontaneous combustion,lifting and transport damage,blasting accident,water inrush and flooding accidents during coal mining is dangerous and harmful factors of the need to guard against.In this paper,LEC method of mine ventilation systems,gas and coal dust explosion prevention systems,anti-fire and water rescue systems,control of water systems,security and surveillance and personnel location systems,blasting equipment,management systems,transportation,lifting systems,electrical,communication links and air pressure,self-help systems were evaluated.For gas explosion,coal dust explosion,water damage,fire,roof,lifting,transportation damage,electrical damage and other major hazard risk assessment carried out.This paper presents a protection layer mining,ventilation and gas control large areas of the region outburst prevention and other security technology,reasonable determination of the coal seam of gas near the floor,high pumping Lane,mined-out area and the wear layer of drainage parameters proposed release hole,pre-pumping heading face drivage,drilling field drainage and other mechanized mining face in local prevention measures and mechanized excavation work.We made a number of coal mine safety management should be pay attention to safety measures and measures.
