我矿自1965年开始使用屏蔽电缆,至今已有8年。先后进货大约总共7000余米,除报废者外,现仍在使用中的尚有5000余米,其中采掘机械用移动电缆占多数。由于数量较少,而且每次进贷数量有限,加之电缆紧张,所以都是随到随用,几千米屏蔽电缆分散在全矿井下与其他电缆混合运行。因此对它的特性,没有深刻的体会。1969年内蒙古电缆厂给我矿屏蔽电缆600米(3×50+1×16,200米,3×35+1×10,300米。3×25+1×10+4×4,100米)。建议我们在一个工作面集中运行,以便作一观察。因此我矿于69年9月准备 E8104工作面时,全部采用了屏蔽电缆,实现了第一个屏蔽电缆工作面。在工作面回采期间对电缆作了初步观察,对它的特点和使用方法有了一定的体会。下面主要对这次运行的过程及结果作一介绍,然后谈谈我们的粗浅体会和认识。
Mine has been using shielded cable since 1965, and has been for 8 years. Has purchased about a total of more than 7,000 meters, in addition to scrapped persons, are still in use, there are still more than 5,000 meters, of which mining machinery with a majority of mobile cables. Due to the small number, and the limited amount of lending each time, combined with the tension of the cable, it is easy to use. Several thousand meters of shielded cables are scattered in the whole mine and mixed with other cables. Therefore, its characteristics, there is no profound experience. In 1969, Inner Mongolia Cable Factory gave me mine shielded cable 600 meters (3 × 50 + 1 × 16,200 meters, 3 × 35 + 1 × 10,300 meters. 3 × 25 + 1 × 10 + 4 × 4,100 meters). Suggest that we run in a centralized operation, in order to make an observation. Therefore, when mine prepared the E8104 face in September, 69, all the shielded cables were used to realize the first shielded cable face. During the mining face during the first observation of the cable, its characteristics and methods of use have some experience. The following mainly on the operation of the process and the results of an introduction, and then talk about our superficial understanding and understanding.
