Longwall Mining Coal Shearer

Longwall Mining Equipment - Coal Shearer

Mining Clients worldwide have strong desire to mine low-seam or thin seam reserves. In some cases, thinner seam overlays the thicker seams. If we mine the thicker firstly, which will cause upward subsidence and make unrecoverable damage to the above thinner seams.

In which kind of conditions that Fully mechanized Longwall Mining technology is urgently needed?

1. the thicker coal has already been mined;

2. sites with valuable coal ore even at small volumes;

3. mine the thin seams to allow access to larger seams;

4. difficult mining sites with low, steeply pitching and faults reserved coal seam

Developed haulage off pan shearer, for the first time achieved a minimum limit of thin seam mining height 0.56m mechanized mining. Successfully widely used in ultra low coal seam below 800mm.

The application of the technology, coal face yields 1.8 times, mining efficiency increased by 3.38 times, tons of coal production cost was reduced by 63%.
