specific Embodiment approach

[0014] The floor limestone karst detection method of the present invention, its preferred specific implementation mode is:

[0015] It includes a signal source, a detector, and a signal processing unit. The signal source is driven by an object that can swim in the water, and randomly swims everywhere in the floor limestone karst;

[0016] The detector is arranged in the underground tunnel of the mine, and is used to detect the signal sent by the signal source, and input the signal to the signal processing unit;

[0017] The signal processing unit processes the received signal to obtain the position of the signal source.

[0018] The object capable of swimming in water can be an aquatic animal capable of withstanding water pressure greater than or equal to 1Mpa, such as one or more of the following aquatic animals:

[0019] Black bream, sturgeon, eel, eel.

[0020] The object capable of swimming in water may also be a mechanical device.

[0021] The signal sources may includ...

specific Embodiment

[0031] The measuring point adopts the explosion source measuring point, and the testing instrument adopts the mining microseismic detector. Specifically include:

[0032] Source point: It consists of two parts: the explosive part and the floating part. The role of the explosive part is to detonate at regular intervals, and a blast will generate a shock wave that travels a long distance in the rock formation; the role of the floating part is to fill in gas to adjust the overall bulk density of the source device so that it is the same as the bulk density of karst water and can be suspended in the rock formation. Karst water.

[0033] Deep-water organisms: It is required to have certain water pressure resistance and be able to withstand the high pressure of underground karst; it is slender and good at swimming, and can swim through small caves. Through the free and random swimming of deep-water organisms in the limestone karst water of the bottom plate, the source point is brou...

Abstract

The invention discloses a base plate limestone karst stationing detection method, comprising a signal source, a detecting instrument and a signal processing unit. The signal source is driven by objects capable of swinging in water, such as living beings, other mechanical devices and the like to randomly walk to each place of the base plate limestone karst; the detecting instrument is arranged in a mine underground roadway and is used for detecting signals transmitted by the signal source and inputting the signals to the signal processing unit; the signal processing unit processes the received signals and obtains the position of the signal source, and can count to obtain developing areas and a distribution rule of the base plate limestone karst by combining with field hydrogeology data and field experience according to the positions of a plurality of signal sources. The invention has simple structure, low cost and lower requirement on construction technical staff, can be popularized at site and is less influenced by geological conditions.

Description

technical field [0001] The invention relates to a karst survey technology, in particular to a detection method for floor limestone karst point distribution. Background technique [0002] The survey method of karst and karst collapse has always been a problem that people are trying to explore. Finding out the spatial location and scale of the underlying karst caves is very important for mines that are threatened by the confined water of the floor limestone karst. Only by clarifying the water-rich law of the floor limestone can effective water control be achieved. [0003] In the prior art, the karst survey method mainly adopts the detection technology mainly based on geophysical prospecting. Including geological radar, microgravity measurement, seismic exploration, direct current exploration, electromagnetic exploration, infrared water exploration technology, advanced horizontal drilling and other methods. [0004] The above-mentioned methods of detecting karst distribution...
