Publication number: 20200370433Abstract: The present invention relates to the field of prevention of a water disaster in coal mining, and discloses a risk evaluation method of an overburden bed-separation water disaster in a mining area. In the prior art, prevention of the bed-separation water disaster is achieved mainly by making bed-separation water “cut-off holes” and “diversion holes” underground; however, the degree of a roof bed-separation water disaster in the mining area has not yet been qualitatively or quantitatively evaluated and analyzed, resulting in blindness of the prevention of the bed-separation water disaster. In order to solve this problem, the present invention provides a risk evaluation method of an overburden bed-separation water disaster in a mining area, which includes the following steps: S1. collecting geological information about strata in the mining area; S2. calculating the height of a water-conducting fissure zone in the mining area; S3.Type: ApplicationFiled: January 25, 2019Publication date: November 26, 2020Applicant: China University of Mining and TechnologyInventors: Wenping LI, Kaifang FAN, Qiqing WANG, Xiaoqin LI, Dongliang ZHAO
