The isolated island working face is surrounded with the goaf and its Surrounding coal column and goaf have a tendency of spontaneous combustion.

Permo-Carboniferous coal measure strata with high coal quality and moderate evolution degree are widely developed in Gubei slope zone, thus this area has the material base to form coal-derived gas accumulations, which have been encountered by several wells.

Site measurement analysis on top-coal movement and displacement in a lower sub-slice isolated island fully mechanized top-coal caving face;

The paper introduces application of light-duty caving Support in remaining coal mining and isolated island working face.

The Positive Islanding Detection Based on Inverter;
