Abstract

The invention provides a coal-bearing stratum coal, oil and gas resource exploiting method and device. The method comprises, according to the occurrence characteristics of coal resources and oil and gas resources in a coal-bearing stratum, determining a coal stratum to be exploited in the coal-bearing stratum and meanwhile determining coal resource exploiting processes as well as oil and gas resource exploiting processes; according to the occurrence characteristics of coal resources and oil and gas resources of the coal stratum to be exploited, determining coal exploiting areas and oil and gas corridor areas; according to the coal resource exploiting processes and the oil and gas resource exploiting processes, determining coal resource exploitation in the coal exploiting areas and oil and gas resource exploitation in the oil and gas corridor areas. The coal-bearing stratum coal, oil and gas resource exploiting method reduces resource damage and waste caused by disordered development, reduces accidents and improve the resource development and utilization efficiency of the coal-bearing stratum.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a method and device for mining coal and oil and gas resources in coal-bearing strata. Background technique [0002] In coal-accumulating basins, coal resources are accompanied by abundant oil and gas resources such as coalbed methane, sandstone gas, and petroleum, and the buried depth of oil and gas resources is greater than that of coal resources, resulting in complex mining procedures for the two resources. For oil and gas development in coal mining areas, on the one hand, it is difficult to drill and construct wells in unstable rock strata overlying the goaf, and on the other hand, the development of mining fissures may easily lead to serious well leakage, resulting in safety accidents; Subsidence of the overlying strata will cause damage to the staggered section of the natural gas extraction well, leakage and explosion of natural gas in the pipeline network, and the influx of ...
