In order to achieve the electrical measurement of descending amount of hydraulic support pillar and distinguish exactly the mine pressure behaviors in fully mechanized mining face,a new displacement monitor of hydraulic support pillar was developed,then its operating principle was introduced and the accuracy analysis was conducted. The accuracy check results showed that the monitor had high stability and large measurement range,the measurement accu-racy scope was from -0.8 mm to 2.7 mm and the accuracy class was 0.3,which met the re-quirement of field measurement accuracy.
