This dating is based on the known presence of Homo erectus in Indonesia by 1.8 million years before the present and in East Asia by 1.36 million years before present, as well as the discovery of stone tools made by proto-humans in the Soan River valley, at Riwat, and in the Pabbi Hills, in present-day Pakistan. Although some older discoveries have been claimed, the suggested dates, based on the dating of fluvial sediments, have not been independently verified. The oldest hominin fossil remains in the Indian subcontinent are those of Homo erectus or Homo heidelbergensis, from the Narmada Valley in central India, and are dated to approximately half a million years ago. Older fossil finds have been claimed, but are considered unreliable. Reviews of archaeological evidence have suggested that occupation of the Indian subcontinent by hominins was sporadic until approximately 700,000 years ago, and was geographically widespread by approximately 250,000 years before the present, from which point onward, archaeological evidence of proto-human presence is widely mentioned. According to a historical demographer of South Asia, Tim Dyson: "Modern human beingsbHomo sapiensboriginated in Africa. Then, intermittently, sometime between 60,000 and 80,000 years ago, tiny groups of them began to enter the north-west of the Indian subcontinent. It seems likely that initially, they came by way of the coast. ... it is virtually certain that there were Homo sapiens in the subcontinent 55,000 years ago, even though the earliest fossils that have been found of them date to only ab ------------------------------ Date: Fri, 18 Sep 2020 11:57:41 -0400 From: "Watt Pro Saver" Subject: New Technology New Technology http://gethardagain.co/lwMWu8zOlmjbth8clx6-ri15D9a9LVQu-fRQwA_ZhOkNYNmI http://gethardagain.co/DUrZA9nt38iGRwm9AJn3sIbxjAV3LZ_2H1DgpRHG7mgNExhW The act of mining required different methods of extraction depending on the mineralogy, geology, and location of the resources. Characteristics such as mineral hardness, the mineral stratification, and access to that mineral will determine the method of extraction. Generally, mining is either done from the surface or underground. Mining can also occur with both surface and underground operations taking place on the same reserve. Mining activity varies as to what method is employed to remove the mineral. Surface mining Surface mining comprises 90% of the world's mineral tonnage output. Also called open pit mining, surface mining is removing minerals in formations that are at or near the surface. Ore retrieval is done by material removal from the land in its natural state. Surface mining often alters the land characteristics, shape, topography, and geological make-up. Surface mining involves quarrying which is excavating minerals by means of machinery such as cutting, cleaving, and breaking. Explosives are usually used to facilitate breakage. Hard rocks such as limestone, sand, gravel, and slate are generally quarried into a series of benches. Strip mining is done on softer minerals such as clays and phosphate are removed through use of mechanical shovels, track dozers, and front end loaders. Softer coal seams can also be extracted this way. With placer mining, minerals can also be removed from the bottoms of lakes, rivers, streams, and even the ocean by dredge mining. In addition, in-situ mining can be done from the surface using dissolving agents on the ore body and retrieving the ore via pumping. The pumped material is then set to leach for further processing. Hydraulic mining is utilized in forms of water jets to wash away either overburden or the ore itself. Mining process Blasting: Explosives are used to break up a rock formation and aid in the collection of ore in a process called blasting. Blasting generally the heat and immense pressure of the detonated explosives to shatter and fracture a rock mass. The type of explosives used in mining are high explosives which vary in composition and performance properties. The mining engineer is responsible for the selection and proper placement of these explosives, in order to maximize efficiency and safety. Blasting occurs in many phases of the mining process, such as the development of infrastructure as well as the production of the ore. ------------------------------ End of alt.music.moxy-fruvous digest V14 #4975 **********************************************
