Strengthen the power supply fan in heading face and avoid unplanned power outages caused gas gauge


For the continuity of the wind. (3) the implementation of intelligent vacuum feed switch intelligent vacuum feed switch timely monitoring of wiring insulation, easy repair and maintenance line, both selective leakage protection, damage or other lines once the insulation is low, the line does not harm, reducing the scope of the accident. 3 results Pansan targeted to the active and effective measures, the reliability of power supply fan in continuous improvement since 2005, put an end to unplanned power outages caused by the gas overrun accidents, driving rate rising for the third Pan Mine development and technical innovation to provide high positioning a powerful guarantee. Fan in such spare capacity, spare fan in another way must be taken from the power supply,[link widoczny dla zalogowanych], main and backup fan in automatic switching. (3) specifically for mixed routes from the central line and substation different bus segments. (4) power lines designed to be simple. 2.2 The implementation of mandatory preventive maintenance of power supply system mandatory preventive maintenance is an effective means to ensure supply reliability, safety and to correctly handle the dialectical relationship between production, efficient production can not be blind because of the neglect of preventive maintenance. Pan Three Mine 4th quarter 2004 daily maintenance from the past become mandatory regular preventive maintenance, monthly maintenance of 14 mining areas 4 and switches specifically for Xianlu, ll a 14, mining area maintenance Biandiansuohun 4 loaded line, 2l maintenance of a 24 paragraph 4 of the Central substation bus, to reduce the production of, maintenance of high voltage substations in the mining area, while simultaneously mining area of low pressure system maintenance to ensure the maintenance of quality 0, the establishment of full-time power dispatcher, emergency maintenance problems encountered in the process, and to develop a detailed maintenance content, maintenance standards and maintenance system. Prevention through the implementation of mandatory maintenance, supply accidents decreased by 78% over last year, put an end to unplanned power outages caused by gas overrun accidents. Practice shows that mandatory preventive maintenance is to ensure reliability of power supply fan in driving face an effective means not only will not affect production, but boost production. 2.3 With Improved supply of science and technology equipment, excavation equipment in the escalating level of driving a single into the continuous improvement of the old fan in power supply can not meet the needs of production equipment, to prevent and avoid the gas gauge, on the fan in the power supply must be improved equipment. (1) rotating fan in the implementation of high-power, increase the air flow as the face for raising the level of driving a single into the same absolute amount of time driving rate increases, the wind also increased the amount of discharge gas, the past About the author: WU Ji Shan (1972 a), Huainan, engineers, Huainan Mining Institute in 1996 graduated from the Department of Mechanical Engineering,[link widoczny dla zalogowanych], has been engaged in the management of coal mining machinery and equipment technology, telephone :0554 -76366661, E-mail: zhannhe74 @ 163. eom.
