Microseismic monitoring of rock mass, such as mines, will provide data about condition of mass on the borders of waste areas at different levels of implementation of mining. The main problems of monitoring are the information absence about condition of mass above waste areas also imperfection of equipment that should provide high accuracy and sensitivity of researches. For example of piezoelectric sensor KD-35 shows to study of one characteristics by means of laboratory test, preliminary calibration and research fieldwork for study of the properties of piezoelectric transducer (sensor) responses on external inducer sources at different distances from sensor.

Key words: piezoelectric sensor, transducers, accelerometer, performance of piezoelectric sensor, calibration, microseismic monitoring of dangerous objects.
