已经深部化的煤矿,如能具备防止进一步深化并且可以反过来向浅部开拓的条件和手段,对于煤矿经营稳定是特别有利的。在北海道比较深的区域开采的煤矿,大多数都在竖井、斜井等周围留有煤量较大的保安煤柱,尤以狭窄内地煤田的煤矿保安煤柱... 已经深部化的煤矿,如能具备防止进一步深化并且可以反过来向浅部开拓的条件和手段,对于煤矿经营稳定是特别有利的。在北海道比较深的区域开采的煤矿,大多数都在竖井、斜井等周围留有煤量较大的保安煤柱,尤以狭窄内地煤田的煤矿保安煤柱的煤量比例更大。 展开更多

The deposit scale in the coal mine shaft usually causes serious accidents, such as making rope broken, cage seized or dropped. To solve this kind of problems, the re-search of the cutting scale mechanism was made, and a new type of removal scale equipment was made with using imported hard alloy material. The cutting experiment and actual cutting show that it can adapt to abominable condition in the shaft, such as narrow space, wet and excessive shaft crevice water and so on, and can work safely and reliably, and has high cutting scale efficiency. It can also cut out the deposit scale in the circular section of shaft. 展开更多
