Yanzhou Mining (Group) Company Jining No. 2 coal mine in complex conditions under the comprehensive mining face safety construction has taken a series of safe and efficient technology. Take high-power back column winch, special unloading platform and multi-winch adjustment to prevent overwhelming the technology to solve the 63 07 large-angle face support carriage transport, installation of the frame and skew frame problems. Make full use of the non-polar rope rope to be recycled along the slot as the primary rope of the tape-dropping, forming once by the rack and laying the conveyor belt once, which greatly simplifies the complex process of once every 200 m of tape installation and greatly reduces many intermediate links and labor Put in. Take effective “one through three” and discharge water measures, 113 under 06 fully mechanized mining face cut 20 m without construction, did not dredge the case of old empty water began to install; cut through the eye to re-perfect the installation of transport equipment and facilities , To complete the entire face installation. 3304 back
