5 underground mining enterprises should establish complete before the end of 2011 to enhance personnel lifting systems video surveillance system, wellhead control room, hoist room, improve staff out of place (wellhead, bottom, middle Ingate, yard, etc. ) video surveillance. 

6. monitoring system to have the data display, transmission, storage, processing, printing, sound and light alarm, control and other functions. 

(Six) underground personnel positioning system. 

1 medium-sized underground mining enterprises shall, prior to the end of June 2012, other underground mining enterprises should be before the end of June 2013 to complete the construction of underground personnel positioning system. The number of staff on duty underground work less than 30 persons, shall establish personnel access well information management systems. 

2 underground personnel positioning system should have the function of dynamic changes in the distribution and regional staff to monitor each job underground. Personnel access well information management system should guarantee accurate knowledge of the number of underground workers in the various regions. 

(Seven) emergency system. 

1 underground mining enterprises should avoid disaster before the end of 2011 to set up a rescue capsule chamber or at least in the middle of each. When single head roadway excavation, tunneling 500m should each set up a disaster prevention or rescue capsule chamber. 

2 Escaping chamber or rescue capsule should be set in place a solid rock hard. Escaping chamber should be able to effectively prevent poisonous gases and water gushing into the mine, and equipped to meet the duty operations officer one week need water, food, equipped with self-rescuer, toxic and hazardous gas detection instruments, emergency medicine, and lighting equipment, as well as direct access to the ground the telephone dispatch room, installation for air, water pipes and set the valve.
