What is the explosive force mining method?
It is a kind of stope method. It also divides the ore block into two parts: mining room and pillar, mining first and then mining. When the ore body inclination angle is between 30° and 50°, the ore cannot be transported by means of gravity, and there are many difficulties in using the room and column method. (For ore bodies with inclined ore bodies 30° to 50°, it is difficult to solve mining operations). In this case, it can be considered to solve the problem by using the explosive force transfer method. The explosive force mining method is to throw the ore into the ore-extracting area by means of the explosive force at the time of falling mine. We call such a method for explosive mining. This mining method is to dig a rock drilling patio at the bottom of the ore body, preferably at half the position of the ore and the rock of the chassis. The advantage of this method of arranging the patio is that there is no downhole, the amount of waste rock is small, and the bottom plate is blasted. Relatively flat, less deposits in the chassis. Fan-shaped blastholes (medium or deep holes) in the rock drilling patio. A 01-38 or EA-100 rig can be used . The work of mining is to push the road upwards. Generally, it is concentrated rock drilling and blasting in several stages. 2 The surrounding rock must be allowed to collapse.
