Lower back pain was a common symptom in dumper operators, as revealed from the questionnaire response. This is likely due to their prolonged exposure to vibration while operating the machine. The present study considered 220 subjects consisting of 110 each in the case and control groups in three coal mines.


Purpose. Two groups of heavy earthmoving equipment operators, transport equipment (dumper) operators and non-transport equipment (drill and shovel) operators, in coal mines are assessed comparatively for their vibration magnitude and possible health …


Objective. Prolonged exposure to hand-transmitted vibration (HTV) is associated with an increased risk of hand-arm vibration syndrome (HAVS). This study aimed to identify the signs and symptoms associated with coal workers using hand-held vibrating tools in a northern China coal mine, and to determine the risk factors for HAVS.


Exposure to whole-body vibration (WBV) negatively impacts the health and safety of exposed mine workers. Off-road mining equipment operates on rough surfaces under harsh operating conditions that produce WBV and mechanical shock. Vibration is often complex, contains many frequencies, occurs in several directions, and changes over time.

The most common types of mining equipment vary depending on whether the work is being carried out above or below ground or mining for gold, metals, coal or crude oil. From drilling machines to excavators, crushing, and grinding equipment, the industry comes complete with all the right mining tools.


Mining machines are now more efficient because updated technology saves energy and reduces the number of harmful chemicals needed to extract desired material from its surroundings. Heavy duty, weather-resistant equipment is still necessary to extract, transport, and process minerals, ores, coal, and precious metals from soil, sand, and rock.

The available equipment is: circular vibrating screen and equal-thickness screen. For coal preparation plants of large and medium-sized mines, equal-thickness screens are preferred. For small factories and mines, circular vibrating screens are selected. The circular vibrating screen has a simple structure, but it is not suitable for large-scale.

Singh 1 conducted an extensive study in six coal mines in India and established the threshold value of vibration (PPV) for different RMR of roof rocks in underground workings for safe and efficient exploitation of coal from opencast and underground mines simultaneously. Established guidelines are based on results of 202 blasts conducted in open ...


MAISHI vibrating mining screen belongs to stainless steel screen. It is often called a vibrating mining screen because it is mostly used for screening and filtration in coal mines, mining, construction and other industries. It can also be called vibrating screen, mining screen, soil screen, aggregate screen and so on.


Figure 2 illustrates VDV(8) measurements for fore-aft (X), lateral (Y), and vertical (Z) whole-body vibration measurements for the 69 dozers in operation at the surface coal mine.Measured as VDV, accelerations in the vertical direction (Z) were greater than horizontal directions (X, Y), with 24 of the dozer measurements, or 35% of measurements, exceeding the …

Non-coal mines and quarries are in a better position due to relatively high frequencies (Adhikari et al, 2005). While no compromise can be made with regard to protection of surface structures from ground vibration, permissible vibration levels should not be unduly restrictive, posing constraints to mining operations.


It is widely used in mines, coal mines, quarries, and other mining industries.
