在向四个现代化的进军中,我矿广大工人、工程技术人员在推广应用喷锚支护新技术多年实践的基础上,结合我矿井下生产特点,学习和运用兄弟矿山的先进经验,通过革新和实践,逐步建成了由下料设施、井下搅拌系统,运料专用斗车、皮带上料机、喷射机和机械手配套设备组成的井上、井下机械化作业线(以下简称作业线)。虽然这条喷射混凝土支护作业线运转的时间还不长、整个作业线的工艺及配套设备还有待今后生产实践中不断改进和完善,然而工业试验初步表明,喷射混凝土支护作业线具有改善喷锚支护作业的劳动条件,提高喷射混凝土的工效等显著优点,有利于做到紧跟掘进工作面,随掘随喷,及时维护。它不仅为喷锚支护这项新技术继续在我矿推广应用开辟了新
In the process of marching toward the four modernizations, based on many years’ practice of popularizing and applying new technology of shotcrete and bolt support, the vast numbers of mine workers and engineers and technicians have learned from and applied the advanced experience of our brothers and mines through innovation And practice, we have gradually built the uphole and downhole mechanized operation lines (hereinafter referred to as operation lines) which are composed of the feeding facilities, the downhole mixing system, the transport vehicle, the belt feeding machine, the jetting machine and the robot supporting equipment. Although this shotcrete support line operation time is not long, the entire line of technology and ancillary equipment remains to be continuously improved and perfected in the future production practice, however, industrial tests show that the shotcrete support operation line with improved spray Anchoring and supporting work of the working conditions, improve the efficiency of shotcrete and other significant advantages, is conducive to be followed by driving face, with the dig with the spray, timely maintenance. It is not only for spraying anchor support this new technology continues to promote the application of mine opened up new applications
