一、我国几个薄矿脉矿山进行快速回采的现状及其获得的成績自1958年以来在某些矿山组织了快速回采的試驗工作,巳收到显著效果。现将各矿山組織快速回采所采取的主要措施和获得的技术經济指标列于表1。从表1列举的资料中看出: 1.由于各矿山具体条件,生产技术水平和采用的措施不同,所以获得的技术經济指标也不同。 2.由于组织快速回采,提高了回采强度116—450％,生产力大大提高; 3.只要采用先进的凿岩技术,改进凿岩爆破参数和严密劳动組織等綜合措施,可以使岩工劳动生产率提高116—218％。
First, the status quo and achievements of several fast-recovery mines in several thin-veined mines in our country Since 1958, experimental work has been organized for quick-recovery in some mines and has achieved remarkable results. The main measures taken and the technical and economic indicators now obtained by the rapid recovery of mines are shown in Table 1. From the data listed in Table 1, we can see: 1. Because of the specific conditions of each mine, the technical level of production and the measures adopted are different, the technical and economic indicators obtained are also different. 2. Due to the quick recovery of the organization, the recovery intensity is increased by 116-450% and the productivity is greatly increased. 3. As long as the advanced drilling technology, the improvement of drilling and blasting parameters and the strict labor organization and other comprehensive measures are adopted, the productivity of the rock work can be increased 116-218%.
