What rocks are rrope impact drill tools suitable for?
Wireline impact drilling tools are particularly suitable for relatively hard geological rocks, such as granite, gneiss, limestone and sandstone. These rocks usually have high hardness and density, which impose high requirements on the drilling efficiency of drilling tools and the service life of drill bits. Wireline impact drill tools are designed to effectively address these challenges, improve drilling efficiency, reduce core clogging, and extend drill bit life. Therefore, in the fields of geological exploration and mining, rope impact drilling tools are widely used in drilling operations of these hard rocks.
Wireline impact drilling tools are suitable for the following geological conditions:
Rock type: Rope impact drilling tools are particularly suitable for harder geological rocks, such as granite, gneiss, limestone and sandstone. The hardness and density of these rocks are relatively high, which places higher requirements on the drilling efficiency of drilling tools and the service life of drill bits.
Geological structure: It is suitable for rock formations with a stratigraphic inclination angle of less than 45 degrees and a stratigraphic plane inclination of less than 25 degrees. In addition, it is also suitable for plains, low mountains and hilly areas with simple structures.

Groundwater: Impact drilling is suitable for areas with relatively shallow groundwater levels, such as wells, weirs, ponds, ponds, etc. In these places, impact drills can effectively cope with the impact of groundwater levels and ensure the smooth progress of drilling operations.
In addition, wireline impact drilling tools have high efficiency in breaking hard salt and non-consolidated heterogeneous rock formations, and are especially suitable for large-diameter drilling in complex formations such as loose pebbles and gravel layers, such as large pebbles, large boulders and other formations. Drilling into clay layers, drilling into sand layers, and drilling into rock layers with developed fissures.

In general, wireline impact drilling tools are suitable for hard and complex geological conditions, can effectively improve drilling efficiency, reduce core clogging, and extend the service life of drill bits. In the fields of geological exploration, mining and construction, rope impact drilling tools play an important role.
