The application discloses a kind of
continuous monitoring methods of
coal mine mining
overburden rock three-dimensional interstice, belong to
coal mining technical field.Through
coal mine
overburden rock multi-position separation layer monitoring device measurement coal seam mining after the three-dimensional interstice of
overburden rock: based on coal seam mining thickness and water conducting fractured zone development height, formulate mining overburden rock interstice monitoring scheme;Perpendicular monitoring borehole is arranged on the surface above the
stoping working face, and coal mine overburden rock multi-position separation layer monitoring device is installed in the borehole;Real-time acquisition, storage and analysis
monitoring data are acquired by
data acquisition box and computer;Based on the advancing distance of
coal mining face, the evolution law of single-hole interstice of mining overburden rock is analyzed;
Kriging interpolation method is used to predict the unknown point interstice of working face according to the multi-hole
monitoring data, and the spatial curved surface
visualization model of mining overburden rock interstice is generated.The application can realize the
continuous monitoring of the distribution characteristics of overburden rock three-dimensional interstice in the process of coal seam mining, and provide a scientific basis for determining the key parameters of grouting and filling.
