Industry guidelines have been developed to provide safe guidelines for vibration and noise produced by mines in urban environments. Monitoring vibration and noise levels at homes and business around the mine can help ensure that your mining activities are within these limits.
Various steps are commonly adopted at construction sites to ensure safety of engineered structures against blast vibrations, e.g. adopting a suitable safe vibration level, developing site-specific attenuation relation, estimating safe charges for different distances, designing blasting pattern, and monitoring vibrations during actual blasting.

Construction and mining activities can cause vibration that varies in intensity depending on several factors. The use of pile driving, vibratory compaction equipment, and blasting typically generates the highest construction- and mining-related ground-borne vibration levels. Because of the impulsive nature
Field measurements utilizing a seat pad accelerometer were made on 61 surface coal mining machines in order to quantify the vibration levels experienced by the operators. These data were combined with information on the statistics of the operating times of these machines in order to compare the ...

Ambient vibration levels in build-ings. Ambient (background) levels of vibrations in buildings due to normal, day-to-day activities usually range from about 0.02 to 0.10 in/sec. Common val-ues measured by the authors are shown in Table 1. Ambient levels due to common oc-cupant activities, such as walking, oc-casional running, and closing doors,
Ground vibrations originating from bench blasting may cause damage to slopes, structures, and underground workings in close proximity to an operating open-pit mine. It is important to monitor and predict ground vibration levels induced by blasting and to take measures to reduce their hazardous effects. The aims of this paper are to determine the weaker protection objects by comparatively ...

There is no South African legislation pertaining to acceptable vibration levels or vibration exposure limits on mining equipment. The European Community Directive 2002/44/EC specifies a daily exposure limit of 5 m s −2 standardised to an 8 h reference period, and an action value of 2.5 m s −2.
A. Vibration Limits: Prior to beginning vibration analysis of coal mining equipment, a review was made of existing vibration standards. No vibration standards or limits were identified that specifically applied to mining equipment. The vibration limits agreed upon were determined after review of ...

A broken piece of equipment can translate to thousands of dollars in associated costs. Real time vibration monitoring of critical equipment in your operation is the best way to prevent downtime, and a data logger which records vibration levels will help prevent equipment damage while it's in transit.
A discussion about setting state or local vibration standards appropriate for a given locale and type of vibration source can be found in the CVDG chapter, Vibration Regulation. Vibration Standards Worldwide. Most developed countries have human-caused (i.e. excepting earthquakes) ground vibration standards for at least some circumstances.
