一、三天轮提升装置 (一)问题的提出 1963年石圪节煤矿被列为全国五个勤俭办企业的模范单位之一,成为全国学习的先进典型,给全矿革命职工带来巨大的鼓舞和动力。在各级党委的领导下,进一步改变了生产工艺的落后面貌,扩大矿井生产能力,发动群众大搞技术革新。当时由于井下采煤方法的改革,要求提升煤的时间集中,能力加大,但当时主井提升装备为一台2米直径双筒绞车、提升一对一吨单层罐笼,年提煤能力只为30万吨,因此,加大主井提升能力就成了当时技术改造,发展生产的关键。
One and Three-day Wheel Lifting Devices (I) PROBLEM PROBLEMS The Shijieji Coal Mine was listed as one of the five model units in China in 1963 to be an advanced model of nationwide learning and brought a great encouragement to the entire mine revolution workers And motivation. Under the leadership of Party committees at all levels, the backwardness of production technology was further changed, the production capacity of mines was expanded, and the mass mobilization of technological innovations was launched. At that time, due to the reform of underground coal mining methods, requiring time to concentrate to enhance the coal, the ability to increase, but then the main shaft hoisting equipment for a 2-meter diameter binocular winch, lifting one to one ton of single-layer cage, 300,000 tons, therefore, increase the main shaft to enhance the ability has become the technological transformation, the key to the development of production.
