建筑物下矸石充填巷采沉陷控制研究

iming at the actuality of plentiful pressed coal under buildings and environment polluted by the piled coal refuse on the ground in our country, based on the analysis of the current mining methods under buildings, the tunnel mining with coal refuse backfilling under buildings was presented. By researched on the principle of the ground subsidence controlled of tunnel mining with coal refuse backfilling, the fundamental of its design was ascertained. Combined with the geological and mining conditions in a certain coal mine, the actual example was analyzed and the ground subsidence was predicted, the results show that applying the tunnel mining with coal refuse backfilling under buildings is feasible and credible.
