1) grouting while tunneling
边掘边注
2) joint excavation and gas drainage
边抽边掘
1.
In view of during excavating the roadway in the low permeability outburst coal seam,the composite index of coal and gas outburst often went beyond and speed of excavation was very slow,the comprehensive outburst prevention technology with deep-hole pre-splitting-control blasting and joint excavation and gas drainage was put forward,and its mechanism was studied at length.
针对在低透气性突出煤层巷道掘进过程中,煤与瓦斯突出综合检测指标经常超限,掘进速度缓慢等问题,提出了深孔预裂控制爆破和巷帮钻孔边抽边掘相结合的综合防突技术,研究了深孔预裂控制爆破技术的作用机理,阐述了深孔预裂控制爆破技术的工艺流程和巷帮钻孔的布置参数。
6) peripheral water injection
边缘注水
1.
Most of oil fields are developed by peripheral water injection,the effects of salt water drive are favorable,and has gained high current oil recovery in low and medium water-cut stage;at present,some old oil fields has approached high water-cut economic limit of secondary oil recovery stage.
多数油田采用边缘注水开发,盐水驱油效果好,中低含水期采出程度高;目前老油田已接近二次采油高含水经济界限。
补充资料：波状(软边)挡边带式输送机
分子式：
CAS号：
性质：带式输送机的一种。在乎输送带的两侧加上有波纹形的软边，中间用隔板隔起来使其呈框形。可使其提升角度几乎不受限制，可达90°角。在提升角度大，运输场地受限制的情况下，采用此种带式输送机有显著的优越性。由于输送带上装有波形软边和隔板，物料装载厚度可以增高。输送带的清扫比较困难，维修比较复杂，不适用于有黏性的细粉物料。
