The invention discloses a coal mine pressure relief and outburst elimination and coal bed methane exploitation system and method for reciprocating linear cutting micro-liberation layer. The system comprises two sets of power speed regulating drive devices (4), a gear rail (3), a power device (11), a reciprocating movement mechanism (12) and a linear cutting gear rack (6), wherein the two sets of power speed regulating drive devices (4) are respectively meshed with the gear rail (3) arranged inside an upper groove (2) and a lower groove (7) though a gear (13), the reciprocating movement mechanism (12) is driven by the power device (11) and is fixed on the top part of the power speed regulating drive device (4) inside the upper groove (2), the two ends of the linear cutting gear rack (6) are respectively connected with the power speed regulating drive devices (4) inside the lower groove (7) by the reciprocating movement mechanism (12). Through the reciprocating movements of the linear cutting gear rack (6), the micro-liberation layer is cut in a coal reservoir (1), and room for pressure relief and outburst elimination is formed. The system is easy to assemble, simple in structure, and automation control is achieved.
Description
technical field [0001] The invention relates to the technical field of pressure relief and outburst elimination in coal mines, in particular to a coal mine outburst elimination method for reciprocating wire-cut micro-liberation layers and a coalbed gas mining system and method, and is especially suitable for gas control of a single coal reservoir with a large thickness. Background technique [0002] As one of my country's energy development strategies, coalbed methane has been listed as an important carrier to replace coal and natural gas resources and promote reforms in energy production and consumption. Coalbed methane is produced in the process of coalification and is stored in the coal seam in the form of adsorption. When the coalbed methane in the coal reservoir is affected by roadway excavation or coal mining operations, it can be excavated from the roadway to the working face in a very short time. Or the sudden rush out of the mining face will cause equipment or perso...
