Drilling

Ingetrol Explorer Jr. HP 75E

Agapito Associates, Inc. (AAI) has the specialized personnel and equipment required for underground and surface drilling for instrumentation installation, resource confirmation, and exploration.  AAI’s equipment is designed for work in confined spaces and can be easily transported and assembled in difficult to access locations.  Our drilling equipment is powered by either diesel, electric, or pneumatic motors so we are able to select the appropriate motor for the available power source or to meet MSHA requirements in “gassy” mines. Our drill rigs are capable of drilling any angle  from vertical up to vertical down.  Drill rig specifications include:

 

SD-1500

  • Ingetrol Explorer Jr. HP 75E—This core drill model is an electro-hydraulic drill with a Chuck “H” head with synchronization for underground work.  This drill utilizes Load Sensing hydraulic technology.  Its nominal depths with an “H” Chuck head are as follows:

    Diameter Depth (ft) Depth (m)
    B  1,312 400
    N W/L  984 300
    H W/L  492 150

     

     

     

     

    Vertical hole drilling with AAI's Longyear CP-65

  • SD-1500—This rig is either diesel- or electric-powered and can be set up on tracks or skids.  This rig can be equipped with either surface or underground masts and winches.

    Diameter Depth (ft) Depth (m)
    A  1,600  488
    B  1,200  366
    N W/L  800  244
    H W/L  450  137

       

  • Boyle Super 300—This rig is powered either pneumatically or electrically and can be set up on tracks or skids.  This drill rig is permissible in “gassy” mines when powered pneumatically.

    Diameter Depth (ft) Depth (m)
    A 1,600  488
    B 1,200  366
    N W/L 800  244
    H W/L 450  137

       

  • CP-65—This core drill is suitable for difficult access overcoring and is permissible for use in “gassy” mines. 

AAI’s field crew consists of experienced drillers with over 80 years of combined experience in coring and specialized drilling.  Our experience base includes drilling holes for installation of instrumentation, overcoring for stress determination, coring for mechanical testing and rock quality, installation of ground monitoring and groundwater sampling and for geologic characterization.   We have experience in coal, hard rock, and industrial mineral mines as well as embankment and concrete dams.
