What charge structure is generally used for cutting to facilitate the throwing of rock slag?

Continuous charging structure. The explosive is continuously loaded along the axial direction of the blast hole. When the depth of the hole exceeds 8m, two explosive charges (bombs) are generally arranged, one at a distance of 0.3-0.5m from the bottom of the hole and the other at a distance of 0.5m from the top of the grain. The advantages are simple operation; The disadvantage is that the crystal grain is low, and it is easy to produce large blocks in the uncharged nozzle part. 2. Sectional charging structure. Dig a deep hole with ... (1). The function of the cut hole is to first break a part of the rock and throw it to the working face. In the first degree of freedom, generally perpendicular to the working face, the charge coefficient (the ratio of charge length to hole depth) is generally 0.45~0.60. If a smooth surface is used ...

This structural arrangement helps readers to understand things as soon as possible. Explanatory text usually ends naturally. Explain clearly ... sometimes you can't use a single method, but a combination of several methods. What method should I start with? ...

Therefore, even a small program defect requires a long redeployment time. When redeploying, in order to ensure each program version ... 1, compare the input costs. Generally, the B/S structure software only has the initial one-time investment cost. For the group, this is conducive to soft. ...

It can be sent and received to achieve the purpose of telemetry and remote control. Therefore, in practical application, the differential structure is often used, which makes the capacitance value of the capacitive sensor with good temperature stability generally independent of the electrode material, which is beneficial to choose the one with low temperature coefficient. ...

Are the walls of the structure all reinforced concrete? What material is used for the wall of frame-shear wall structure depends on whether the wall is shear wall or not. All walls designed to resist the shear force of buildings (usually considered as earthquake resistance) are collectively called shear walls, which usually ...

It is beneficial to make up for the deficiency of specialty setting in today's university education. "in the late 1990 s, in order to realize the great significance from the Soviet union ... after all, structural contradictions cannot be solved by one party. In the survey, when asked "which policy should be adhered to for a long time" ...
