Thailand Pollution Control Department (PCD), the national agency within Thailand’s Ministry of Natural Resources and Environment, has enjoyed a long working relationship with 01dB, initiated and nurtured by Acoem’s Asia Managing Director, Patrice Pischedda. After consultation with Patrice, PCD was quick to recommend Acoem’s new ORION vibration monitoring system as the best way to assess the impact that the mining explosions were having on the site. Orion was used in conjunction with an external sensor, the triaxial seismometer, to capture the most accurate vibration data.
Ultimately, the goal was to establish whether the mining company was adhering to DIN4150 regulation standards and that the resultant peak particle velocity (PPV) was within an acceptable range.
ORION’s portability and ease of use was a great advantage for this monitoring project. Within a few days PCD could assess that the vibration impact on the site was within the legal parameters and report back to the Government and the temple authorities. PCD will carry on maintaining the integrity of this historic site and has already utilized ORION to ensure compliance of environmental regulations by industry at other sites.
