有关钢丝绳罐道的张紧力和刚性系数,《煤矿安全规程》第336条已作了具体规定,此规定同样适用于建井时期的吊桶稳绳。虽然在贯彻这一规定时还有一些技术问题需要解决(详见本刊1981年第4期《凿井稳绳的安全问题》一文),但从施工单位的现实情况出发,对于稳绳的张紧力,应该有一个测定方法,以保证施工安全。下面介绍一种利用振动波来测定稳绳张紧力的方法。
Regarding the tensioning force and the rigidity coefficient of the ropeway, Article 336 of the Coal Mine Safety Code has made specific provisions, and the same applies to the bucket stabilizing rope during the well construction period. Although there are still some technical problems to be solved when implementing this regulation (for details, please refer to the article “Safety of Sinking and Stabilizing Sinking”, No. 4, 1981), but based on the reality of the construction unit, Tight, there should be a measurement method to ensure construction safety. The following describes a method of using vibratory waves to determine the tension of a steady rope.
