Abstract
The application discloses a shallow coal mine overburden three-zone division visual testing method and system, relates to the stratum testing technical field, and provides the shallow coal mine overburden three-zone division visual testing method and system, utilizes the vertical analysis tube hole formed by initial exploration punching, realizes one hole with multiple uses, and effectively guides the coal mine safety construction and long-term healthy operation in the loess area, and compared with the monitoring mode of the artificial single-point drilling in the prior art, the operation is more convenient; the three-zone monitoring tube can collect continuous monitoring overburden three-zone distribution and deformation law by adopting the mode of bilateral three-zone monitoring tube arrangement, compared with the monitoring mode of the artificial single-point drilling in the prior art, has the advantages of complete and accurate monitoring data, long monitoring time and the like.
