  • Noise Pollution and Its Control in Mining

    The most noise generating equipment underground are the haulage, ventilators-main, auxiliary and forcing fans, conveyor transfer points, cutting and drilling machines. The ambient noise level due to different operations in underground mines varies within 80-104 dBA.

    This will enable you to record the noise levels during mining hours. By measuring the noise levels on the boundary, With sufficient noise monitoring equipment of the right type, you can eliminate most complaints. You can also handle the ones you do receive in a timely fashion. It is not a one-size-fits-all approach, as every mine and its surroundings are different. But it is a challenge

    noise levels of various mining equipment. It is recommended that noise measurements of operating equipment be conducted and these measurements documented. Measurements should include exposure (dB) and the amount of exposure (time) 3 . 1 NIHL impacts. Discussion points • Difficulty in following instructions, unable to hear the instructions very clearly. • Can hear a faint ringing or buzzing

  • Management of noise in Western Australian mining

    There is a regulatory requirement for specific action to be taken when people are exposed to either: • an average noise level of more than 85 dB(A) for an eight- hour working day (L Aeq,8h) or • a peak noise level in excess of 140 dB(lin).

  • Heavy Construction Equipment Noise Study Using Dosimetry

    Sound levels associated with heavy construction equipment range from 80 to 120 dB(A) and power tools commonly used in construction produce sound levels up to 115 dB(A). (1)

    Noise Levels for Common Equipment The following table can be used to determine if employees should participate in the University of Florida’s Hearing Conservation Program (HCP). If an employee’s use of equipment exceeds the allowable time more than two times per month, that employee needs to be included in the HCP. If an employee uses a piece of equipment that exceeds 85 decibels (dBA

  • Noise and Silica Exposures DEOHS Home

    The new rule requires that mine operators enroll miners in a hearing protection program if they are exposed to an average sound level of 85 decibels (dBA) or more during an eight-hour period. In order to determine average sound level, workplace noise monitoring is required.

    *Work can only be carried out between 1900 and 2100 hours if it is of an urgent nature and necessary for the effective carrying out of mining operations, and the noise conditions are met. L 10 is the noise level which is equalled or exceeded for 10% of the measurement time.

  • Mining Noise Monitoring Larson Davis

    Mining Noise Monitoring . The management of noise from mining operations is recognized as a fundamental responsibility of the mining industry. Implementing a noise management system that includes noise surveys, day and night noise mitigation, and some level of noise monitoring is a primary function that is required to meet environmental impact standards in most locations.

  • Applications of Noise Control in the Mining Industry

    In fact, it is currently estimated that 80% of US miners work in an environment where the time-weighted noise average exceeds 85 dB, and in 25% of these cases the workers are exposed to noise levels of 90dB or higher (McBride, 2004).
