Assessment of quarry volume using 2-D resistivity imaging method
A geophysical survey was carried out at Masai quarry, Johor Darul Takzim to estimate the volume of overburden and rock can be excavated. A total of 6 survey lines were conducted in the study area using 2-D resistivity imaging; carried out with pole-dipole array, 5 m minimum electrode spacing with AB...

| Summary: | A geophysical survey was carried out at Masai quarry, Johor Darul Takzim to estimate the volume of overburden and rock can be excavated. A total of 6 survey lines were conducted in the study area using 2-D resistivity imaging; carried out with pole-dipole array, 5 m minimum electrode spacing with ABEM SAS4000 system. The results show the study area was divided into two main zones. The first zone was top layer/residual soil with resistivity value of <700 Ωm. It is consisted of saturated zone with resistivity value of 30-100 Ωm and boulders with resistivity value of > 700 Ωm. The second zone was fractured granitic bedrock with resistivity value of >1000 Ωm and depth of 10-75 m. The overburden consists of residual soil which mixed with boulders. The estimated volume of the overburden is 9,811,831.15 m3. |
