Problems solved by technology
In particular, if the traditional stage-opening mining method arranges the ore-collecting roadway and the ore-out approach at the same height of the track-developed roadway, the trackless equipment will be loaded into the mine car of the track-developed roadway after loading, which will greatly affect the safety of the trackless equipment. Production efficiency, it is necessary to solve the connection problem between the tracked and trackless mining system

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings.
[0017] see attached figure 1 , attached figure 2 , attached image 3 , attached Figure 4 and attached Figure 5 , the specific use case of the track and trackless coupling bottom mining system proposed by the present invention is the bottom mining system of the staged open-field mining method of a certain mine:
[0018] (1) The size of the ore block is 50-100m×70m, the length of the ore block is 50-100m, and the height is 70m.
[0019] (2) Mining quasi-cutting project: On the basis of the existing track development roadway 7, the layout position of the trackless mining quasi-system is increased by one section, and the section ramp 10 is constructed from the track development roadway 7 to the first section, In the first section, construct the sectional chute connection lane 1 and the sectional chute 9, then excavate the sectional level road 2 and the ore outlet 3...

The invention discloses a track and trackless coupled bottom ore removal system. On the basis of a track development system which is formed, the configuration position of a trackless accurate mining system is raised by a subsection. A subsection inclined roadway is constructed from a track development tunnel to a first subsection, and the trackless accurate mining system is constructed in the subsection. Before stopping is conducted in a stope, a sublayer is firstly mined, an artificial false bottom is built by using reinforced concrete, then a triangular ore pillar at a hanging side of the near ore body is mined, and an ore gathering trench is built by using broken stones. The ore backstopped in the stope is loaded by trackless equipment, poured in a subsection jack shaft, delivered to an underground crushing station through a mine car in the track development tunnel, and finally hoisted to the ground through a skip bucket. The ore removal system is high in safety and ore removal capability and low in resource dilution.
Description
technical field [0001] The invention relates to a bottom ore extraction system, in particular to a bottom ore extraction system with track and trackless coupling, which is mainly suitable for the bottom ore extraction system of the staged open-field mining method. technical background [0002] After the rail mining mine has formed a rail development system, the introduction of trackless equipment for mining and solving the connection between the trackless mining system and the rail mining system has become a problem for mines. Especially in the traditional staged open-field mining method, if the ore collecting roadway and the ore outlet approach are arranged at the same height of the track development roadway, the trackless equipment will be poured into the mine car of the track development roadway after loading, which will greatly affect the performance of the trackless equipment. In order to improve production efficiency, it is necessary to solve the connection problem bet...
