However, the caving maybe happen because of too large transmogrification and rheologic fracture to high crustal stres.

统一流变断裂准则，最终形成了诱导条件下节理岩体持续规模自然判据。

Since the method causes serious depletion of ore during mining of upper plate,the inclined cutting raise heading together with inclined medium or deep hole kerve is suggested.

以无底柱为代表的法中,切割拉槽至重要,而目前无底柱多用垂直切割天井与切割平巷并配以中深孔联合拉槽的切割方法,但该方法在对体上盘回过程中损失贫化较。
