Abstract

The invention relates to a passive detector system and an embedded method, belongs to the underground construction equipment field and especially relates to a coal-mine underground horizontal deep-hole multichannel passive detector system and an embedded method thereof. The system comprises a traction head and a detector apparatus, wherein the traction head is provided with a traction pulley and a traction head inflation air bag used for fixing the traction head in a hole after air inflation; the detector apparatus includes several detectors which are connected in series through a connection device; the detectors are provided with detector inflation air bags used for fixing the detectors in the hole after the air inflation; and one end of the connection device is winded around and arranged on the traction pulley. By using the system and the method, a current situation of coal-mine underground seismic exploration construction is greatly improved, which promotes development and application of a coal-mine underground seismic exploration technology.

Description

technical field [0001] The invention relates to a passive geophone system and an embedding method, belonging to the field of underground construction equipment, in particular to a horizontal deep hole multi-channel passive geophone system and an embedding method in a coal mine underground. Background technique [0002] At present, in the embedment device of the horizontal well geophone in the coal mine, the burial depth of the geophone is shallow, generally less than 2 meters, and it is impossible to embed the deep hole, which limits the application of mine seismic detection. Geophones are sensors used to extract formation vibration signals in seismic exploration. In order to obtain high-quality seismic signals, the tight coupling between the geophone and the hole wall plays a decisive role. Therefore, good coupling of the geophone must be achieved. On the other hand, when the wellhead is deep, it is difficult for the geophone to be sent into the well, which affects the con...
