Jade depression Iron Mine Blasting Safety and Management

While loading and unloading; (3) shaft and inclined transport blasting materials, its speed must not exceed 1m / s; (4) electric locomotive transportation, loading trunk of blasting equipment and motor vehicles are separated by two empty, explosives and bombing of the same train transportation guide, they must be separated by empty. (5) transportation of motor vehicles before and after blasting material to set up \(6) prohibit the equipment stays in the wellhead and the shaft bottom; (7) the number of blasting material design should be stacked in designated locations, respectively, and a personal care connection charge phase 3.1.2 (1) Used for each charge grounding wire to prevent the drug delivery tube from the risk of electrostatic effects present f; (2) detonating cord can only use a sharp knife cutting, is strictly prohibited with stones, iron drop; (3) volume to the drug when the hole filled, except wood stick packing, non-iron pipe with a drill rod or; (4) Nonel into the hole, its sub-labels in order to stay in the orifice of external review; (5) charge filling process after acceptance by the technical staff, construction personnel be evacuated; (6) To ensure the quality of the connection, the connection done by technical personnel to operate; (\with two fuses, the length (according to design requirements) shall not be less than 15m; (9) after initiation network connection, a comprehensive inspection by the chief engineer organizations, non-compliance with technical requirements, re-connected until the table cell so far. 3.2 Initiation ① The head of the commander in chief should be responsible for reporting the completion of the case; ② detonating blasting with the passing engineer, chief engineer checked to confirm correct; ③ the normal operation of ventilation; ④ shaft cage has stopped upgrading Master location at the wellhead; ⑤ time until the time of initiation, initiation commander issued the command. detonates next to the relevant person in charge of monitoring, engineers from the blasting fuse lit. 4 4.1 The development of various preventive measures to guarantee the system checks at each level (1) establish a quality assurance system, the quality of accident prevention. blasting the success and quality of construction has a close relationship. because the blasting problems, not only affect the blast effect, but would also produce misfire phenomenon, which to the future safety serious troubles. solid this, we must establish a quality assurance system (see Figure 2), to prevent mass incidents. (2) the establishment of safety assurance system (see Figure 3) to prevent injuries. 4.2 strict accordance with procedures 54 Mine design and construction of large ink bowl construction quality assurance system to ensure that cars kill f --- 1 body falling into the amount of salt to the j chu r_ Gui Fort Tuo - Korea ---- I called the technical requirements for construction guidance Libo 2 Kids in the quality of core Kids in around 3 assurance system to prevent harm to the safety assurance system husband blasting blasting around a large construction time. According to the different burst size, under normal circumstances, the range in the scorpionfish ~ 72h, once the construction work on three shifts. The main process to go through more than a dozen procedure. Figure (4). 4.3 The implementation of safety confirmation system for safety confirmation system is to achieve an effective safety measures 6 1998 4, Kids in the main process of blasting Kids in large facilities. jade depression Iron Blasting project from the design] interesting work, initiation to go through several links, but each have to go through the security aspect is confirmed, before carrying out the next step. Practice has proved that the implementation of safety confirmation system to effectively avoid the kinds of accidents. 4.4 security application security system works is the prediction of modern science and safety system engineering safety management. this. jade ore wa applied the principles of safety system engineering for large blasting a systematic analysis to understand the potential system dangerous and cause of the accident of insecurity. mainly from the environment, equipment, people management (see Table 1,2,3,4) in four areas; take comprehensive measures to eliminate hidden dangers. In this way, will be able to reduce the possibility of accident to a minimum, to achieve the best safety results. slaughtered 6 afraid of 1998 gold mine design and construction of the first of 55 Received Date 19980720 Liu will come.
