一、试验及使用情况为了解电耙子的应用范围,我们在试验时选择了不同的作业地点,如山外剥离、坑内倾斜或缓倾斜的天井、中段采鑛法、鑛壁充填采鑛法等处进行了试验并肯定了电耙子的应用范围是很广泛的。今将试验中的一切情况分述如下:(一)山外剥离试验情况:1.地质概况:岩石是矽酸钙石灰岩,一般硬度在4度左右,爆破后的粒度直径平均约达300公厘左右,最大者700～900公厘,最小者100公厘以下。剥禽面的坡
First, the test and the use of In order to understand the scope of application of electric rake, we chose different test sites in the operation, such as off-hill, pit pitched or gently inclined pavement, the middle mining method, mining and other mining methods Experiments were carried out to confirm that the range of application of electric rakes is very wide. The conditions of the test will be described as follows: (a) off-hill test conditions: 1. Geological Overview: rock is calcium silicate limestone, the general hardness of about 4 degrees, after blasting an average particle size of about 300 mm About 700 to 900 mm maximum, the smallest 100 mm below.
