大采深“针状”陷落柱特大突水治理技术探讨

Discuss on Water Bursting Control Technology of Deep Mining “Needle-Like” Collapse Column

经过近几十年的开采,我国浅部煤炭资源已所剩无几,转而开采深部煤炭资源。目前我国有很多矿井开采深度接近或超过1 000 m,煤层所处的地质和水文地质条件更加复杂,开采稍有不慎,就会诱发底板奥灰特大突水事故,造成重大的损失。文中提出一套"圈"、"探"、"校"、"支"、"定"、"堵"、"检"、"排"相结合的大采深"针状"陷落柱特大突水治理技术,在某矿大采深"针状"陷落柱特大突水治理实践中已取得成功。

After decades of exploitation, shallow coal resources have been left less. Instead, it begins to mine deep coal resources. At present our country has a lot of mining depth close to or more than 1 000 m. Seam geological and hydrological geological conditions are more complex. Carelessly mining activity can cause Ordovician limestone water inrush, which causes significant loss. Puts forward a set of ＂ring＂ ,＂ sound＂ ,＂ school＂, ＂branch＂, ＂set＂ ,＂ blocking＂ ,＂ check＂ ,＂ row＂ the combination of deep mining ＂needle-like＂ collapse column water bursting control technology, and successfully applies to large mining depth ＂needle-like＂ collapse column water bursting management practice, for the full play of deep mine economic benefits is of great realistic significance.
