Machine-blast combined mining device for fully-mechanized coal mining working face

Abstract

The invention discloses a machine-blast combined mining device for a fully-mechanized coal mining working face. The problems that an existing rock drilling device is uneven in stressing, influences the running stability, can not meet the machine-blast combined mining requirement and the like are solved. The machine-blast combined mining device comprises a supporting platform, a rock drilling device, a hydraulic support column, a motor with a brake and a hydraulic control device, wherein the supporting platform is assembled on a ledge and a pin rail of a scraper conveyer and driven by the motor with the brake to move in the length direction of the scraper conveyer. According to the machine-blast combined mining device for the fully-mechanized coal mining working face, an original telescopic cantilever single supporting structure is replaced with linkage-type double supporting arms, and by cooperating with telescoping of an angle adjusting hydraulic cylinder and a lifting hydraulic cylinder, steady vertical lifting of the rock drilling device is achieved; the machine-blast combined mining device is reasonable in design, compact in structure, balanced in stressing, convenient and fast to assemble and disassemble, flexible to move, precise in positioning and stable in operation, can safely and reliably cooperate with drilling and blasting work of a tunnel cross section, can meet the quick assembling, disassembling and moving requirements of machine-blast combined mining work, and significantly improves the production efficiency and the work quality of the fully-mechanized coal mining working face.

Description

technical field [0001] The present invention relates to a kind of special equipment for coal mine fully-mechanized mining operation face for mining the liberated layer for gas drainage, especially a fully-mechanized mining operation face machine gun combined mining device, which is suitable for the condition that the entire operation face is rocky, It meets the high requirements of rapid drilling of the coal (rock) wall of the working face, and then releases vibration and loose guns, and assists the shearer to cut rock. The utility model belongs to the technical field of fully mechanized rock mining machinery and drilling cars. Background technique [0002] At present, in coal mine production, faults are an important factor affecting the advance rate of fully mechanized mining operations, especially in mining areas with complex geological conditions and many faults. Under the condition that the entire working surface of the liberated layer mined by gas drainage is rocky, ra...
