1983年煤炭部第1029号文明确规定了井下使用的提升机或绞车必须是防爆的,现用绞车也必须限期达到防爆要求。 目前,煤炭系统井下使用的非防爆绞车数量相当大,若全部换新的防爆绞车,耗资巨大,影响生产时间又长,显然不可取。解决绞车防爆的较好办法是充分利用现用设备和峒室,走防爆化改造的路子,用较少的资金和少影响生产的办法,使在用绞车达到防爆要求。
In 1983, the Ministry of Coal No. 1029 clearly stipulated that the hoisting machine or winch used in the underground must be explosion-proof, and the existing winches must also meet the explosion-proof requirements within a time limit. At present, the number of non-explosion-proof winches used underground in the coal system is quite large. If all the new explosion-proof winches are expensive and affect the long production time, obviously it is not desirable. A better way to solve the problem of explosion-proof winches is to make full use of existing equipment and halls, to take the approach of explosion-proof transformation and to make the use of winches to achieve explosion-proof requirements with less capital and less impact on production.
