What regulations should be met when applying the segmental empty field mining method?
Plastic Crates Making Machines
Meticulous division of labour, consecutive processes, professional of manufacture and high standard equipment ensure the high quality of the machine.
Factory introduced high precision maching tools, with the equipment of cutting machine tools, heattreating facilities, check out test sets and painting facilities, the processing ability for middle and large size machine, reach a high level in plastic industry while the quality if the machine is ensured at the same time.
Middle size machine can produce differnt design of crates and containers, videos can be provided.
Vertification of many year's market application, optimal combination configuration, stable, reliable and durable system with the characteristics of high efficiency, energy saving, low voice and strong power.
The strengthening design of template is carried out through multiple times of optimization design of major components such as template, based on the analysis of finite element software, which both guarantee the lifetime of template and protected mould.
High rigid template adopts the structure with coexistence of installation screw hole and T-shaped groove.
The tie rod of each machine model has passed the test by professional testing organization, which means that, the deflection of tie rod is within reasonable scope while guaranteeing the operation of machine.

2 The steeply inclined ore body with stable ore should adopt segmental rock drilling and stage mining; for ore body with poor stability or inclination, segmental rock drilling and segmental mining should be adopted;
The height of the 3 sections shall be determined comprehensively according to the rock drilling depth of the rock drilling equipment and the inclination angle of the ore body;
4 The upper and lower adjacent stages of the same ore body and the ore and pillar arrangement of adjacent parallel ore bodies in the same stage shall have the same specifications, and the upper and lower sides and the front and rear shall correspond to each other;
5 Except for the roadway that is used for mining, transportation, filling and ventilation, other roadways shall not be dug in the top pillar of the stope .
