簡介：

天井鉆進(jìn)法是一種鉆鑿大直徑孔眼到地表或貫通夾層的極具安全性和經(jīng)濟(jì)性的鉆進(jìn)方式，典型使用于非爆破方式采礦業(yè)或夾層間循環(huán)孔挖掘，或建造通風(fēng)井、礦井過道、人行巷道和水渠等。天井鉆進(jìn)用途相當(dāng)多，作為一種回轉(zhuǎn)鉆進(jìn)方式，已被全世界范圍內(nèi)礦場、水電站和市政基建工程所接納。

最常用的天井鉆進(jìn)法是領(lǐng)眼上擴法，將天井鉆機安置于需要慣通的層面之間的上層，用密封軸承領(lǐng)眼牙輪鉆頭鉆鑿領(lǐng)眼孔。當(dāng)領(lǐng)眼鉆具慣通到達(dá)目標(biāo)層的空曠處后，將領(lǐng)眼牙輪鉆頭卸去換上所需孔徑的滾刀刀盤，將其連上鉆柱后沿著鉆機方向向上鉆進(jìn)。刀盤鉆進(jìn)中產(chǎn)生的渣屑掉進(jìn)準(zhǔn)備在下層地面卡車?yán)铩?/p>

傲石捷的滾刀是為多種尺寸的（涵蓋從0.6米到12米直徑）刀盤設(shè)計制造，既可用于水平鉆進(jìn)，也可以用于垂直鉆進(jìn)，既可用于領(lǐng)眼擴孔鉆進(jìn)，也能用于盲打鉆進(jìn)。最優(yōu)化的切削結(jié)構(gòu)設(shè)計使?jié)L刀可以適用任何地層，僅需根據(jù)不同地層對滾刀的布齒間距進(jìn)行修改。G和N組合的滾刀混合使用時，可以根據(jù)刀盤進(jìn)行任意的間距組合，達(dá)到更好的進(jìn)尺效率和刀盤韌性。這些滾刀均采用最新技術(shù)設(shè)計，具有最佳性能。

此外，傲石捷能夠通過對客戶提供的巖層信息和天井鉆機技術(shù)參數(shù)進(jìn)行分析，然后重新設(shè)計出最適合他們的滾刀、以獲取最佳切削結(jié)構(gòu)和齒排間距以確保達(dá)到最佳的進(jìn)尺和使用壽命組合，將單位鉆進(jìn)成本降至最低。

General Introduction:

Raise Bore Drilling is extremely safe and economical drilling method to open large diameter holes to the surface or one underground level to another, typically used in mining operations, to excavate a circular hole between two levels of a mine without the use of explosives, or constructing ventilation shafts, ore passes, manways and penstocks. Raise bore drilling is quite versatile and has gained worldwide acceptance as the preferred rotary drilling method at mines, power generation plants and civil infrastructure projects.

The mostly used raise bore method is pre-drilled pilot-hole reaming, in which a raise bore machine is set up on the upper level of the two levels to be connected. A pilot hole is drilled by a sealed bearing pilot tricone bits to the lower level. Once the drill string has broken into the opening on the target level, the pilot bit would be removed and a reamer head with roller cutters, of required diameter of the excavation, is connected to the drill string and raised back up towards the raise bore drilling machine. The debris and cuttings from the reamer head during drilling fall on to a truck prepared on the floor of the lower level. 

Acdrills’ Raisebore Roller Cutters are designed and manufactured for a wide range of reaming heads, varying in sizes from 0.6 to 12 meters in diameter, to be used in, from horizontal TBM boring to vertical drilling, either pre-drilled pilot hole raise bore reaming or blind shaft sinking boring types. Designed for optimum performance in all types of rock formations with varying spacing between the rows of tungsten-carbide inserts, the roller cutters are engineered for many type of Raisebore Head configuration. The G and N Roller Cutters, can be used in variable space combination on any one reaming head, which delivers better rates of penetration as well as increased toughness. These cutters are designed and manufactured using the latest technology and will deliver optimum performance.

Besides, by analyzing the given geological rock formation information of the ground and the type of raise bore machines parameters to be used, Acedrills can re-design the most appropriate raise bore rollers with optimum cutter configuration and most suitable cutting spacing to ensure that the highest penetration rate combined with longest service life, so as to minimize the cost per cubic meter for driller.
