Abstract:

Dalam pelaksanaan suatu proyek jalan tol diperlukan ketersidiaan material perkerasan yang cukup, maka dengan itu berdasarkan pemilihan lokasi quarry yang direncanakan dipilih salah satu gunung atau bukit yang bisa diambil material batu untuk support proyek tersebut. Dalam melaksanakan operasional quarry crusher stone perlu disediakan beberapa alat berat untuk mensupport proses pekerjaan tersebut. Maka dalam pembahasan jurnal kali ini ditekankan pemilihan alat yang tepat dalam pengoperasian quarry crusher stone.

Abstract:

Stone crushing industry plays a vital role in the economy and urban development of fast developing countries like India. Stone mines and crushers in India are located around major cities and roughly employ around 5,00,000 peoples throughout the country. However this employment generating industry also happens to be one of the most dust generating activity and also a precursor to the respiratory disease, silicosis. This study was undertaken with an objective to estimate the personal exposure of the workers to silica laden dust in this industry sector. Personal dust sampling (n=11) and (n=6) was

Abstract:

This study investigated the suitability of Trabzon stone, which is used as a building stone in many areas in and around Trabzon province, as an aggregate. It was found that the uniaxial compressive strength values of the samples taken from the quarry were 87-130 MPa, P-wave velocities were 5048-5642 m/s, density value was 2.58 g/cm3, apparent porosity values were 2.77-4.54%, water absorption values by weight were 1.04-1.78% and water absorption value by mass was 2.0%. Weight loss in the freeze-thaw test was 0.36%, weight loss in the wet-dry test was 0.22%, loss in the magnesium sulfate test wa

Wide-angle recordings of small, multiple-hole blasts at dimension-stone quarries in the Elberton granite show coherent reflections at offsets between 7 and 15 km. In contrast with much larger blasts at crushed-stone quarries, this type of blast is fired without delays between holes. The data were recorded with an array of twenty portable seismographs using three-component, 4.5-Hz geophones. Migration of source gathers for two of the blasts shows a number of subhorizontal interfaces at depths between 2 and 4 km that may represent a layered complex near the base of the granite.

This geological massif consists almost entirely of metamorphic and igneous rocks, the bulk of which are deeply processed by ultrametamorphic processes, including granitization and selective anathexis, which caused the formation of local crustal magmas.

In the case of a limited road service life, it appears economically unfeasible to provide a strong cement-concrete subgrade.

In order to perform calculations of stresses, arising at a great depth in the subgrade of the technological road under the influence of heavy-duty vehicle wheels, it is necessary to use appropriate mathematical models.
