Quarry Line To Ground Distance

The concern of damage from ground vibration, airblast, and flyrock from blasting are a major concern to both the nearby landowners and ODOT as the quarry owner. In most cases these concerns are based on misunderstandings and unsubstantiated fears resulting from a lack of information. The purpose of this handout is to help illustrate

Quote: "If your quarry goes to ground, leave no ground to go to."

The drilled burden is the distance from the borehole to the nearest free face. This is typically looked at in a plan view or in a two-dimensional realm. Improper rhythmic timing practices can lead to worse blasts, causing stemming blow out, uplift, poor backbreak and higher ground vibration.

CFR §192.325(a), "Each transmission line must be installed with at least 12 inches (305 millimeters) of clearance from any other underground structure not associated with the transmission line. If this clearance cannot be attained, the transmission line must be protected from damage that might result from the proximity of the other structure."

The typical way of combining distance and explosive energy is to divide the true distance by the square root of the maximum explosive charge weight per delay to obtain a normalized or scaled distance (ISEE, 1998) as follows: (1) SD = d / W 2 where: SD is the scaled distance (in m/kg 0.5); d is the true distance from shot to specific location ...

Setback variances refer to the distance that your structure must be set back from the property line. This distance is usually determined by your local building codes, and it varies depending on the location and type of property. To navigate setback variances, you should first research the specific regulations in your area. This will give you a ...

rely on distance elements only; these schemes also rely on ground directional (67G), a unit that provides overcurrent higher fault resistance (Rf) detecting capabilities than ground distance elements of any shape [3]. Generally, high Rf faults have been associated with - single line-to-ground faults (AG, BG, CG). For these faults, the

Calculating ground distance accurately is essential for navigation and planning. Whether you're a hiker, a pilot, or simply curious about the distance between two points, understanding how to calculate ground distance is a valuable skill. Factual data: Ground distance can be calculated using the distance formula, which is d = rt, where d is distance,

After that, in the ground, a wave motion is produced by the strain waves conveyed to the adjacent rocks (Duvall and Petkof 1959). The strain waves are propagated as the elastic wave when the stress wave intensity reduces to the ground level (Dowding 1985). These waves are known as ground vibration. Normally, ground vibration can be recorded ...
