一九七五年三月,在长沙矿山研究院和山西长治机修厂的配合下,我矿成立了“三结合”试验小组,对山西长治机修厂试生产的FZY—100型装药器,进行了应用情况标定,仅用了十四天时间,按照试验大纲要求,完成了地表喷药与坑内生产应用的技术标定工作。地表喷药是与现场生产中一直使用的FZY—1型装药器进行对比试验的。从标定的结果看(表一),在相近条件下,FZY—100型装药器比FZY—1型装药器出药快而匀。坑内在无底柱分段崩落法矿房中进行装药试验,共标定10排80个炮孔,总孔深
In March 1975, with the cooperation of Changsha Research Institute of Mines and Shanxi Changzhi Machine Repair Factory, the mine set up a “three-in-one” test group to conduct trial production of the FZY-100 type drug loader at Shanxi Changzhi Machinery Factory The application of calibration, only fourteen days time, in accordance with the requirements of the test outline, completed the surface spraying and pit production technology calibration work. Surface spraying is carried out in field production has been used FZY-1-type chargers for comparative testing. From the calibration results (Table 1), in similar conditions, FZY-100 type charge faster and more uniform than the FZY-1 type charge. Pits within the pillar-free subsidence caving mining experiments, a total of 10 rows of 80 calibrated hole, the total hole depth
