Mining Industry


Mining Industry

Mining is a site-specific economic activity creating wealth from the extraction of nonrenewable resources from land and sea. The boundaries of the mining industry are imprecise. It conventionally excludes oil, gas, and water, but coal and uranium are normally included. Bulk construction materials and stone are extracted in the same fashion as other minerals, and the volume of their output exceeds that of most other minerals, but they are usually excluded from definitions of the industry. The downstream boundaries are somewhat indeterminate, depending on processes, corporate structure and end uses. Mines usually produce ores that require further processing rather than finished products and the ores may contain one or several economic products. The usable materials are often a small proportion of the ore mined. There are various methods of mining, each suited to the specific circumstances of each mineral deposit, and each with different cost structures. Most minerals are either extracted from open workings in which the overburden is first stripped away to expose the economic ore, or from underground workings that access the ore through shafts or tunnels. Substantial volumes of waste are mined as well as ores, particularly in open pit mines producing base and precious metals.


GLOBAL FEATURES

Ore deposits are not evenly distributed around the globe, with different minerals concentrated in specific geological environments. Typically, deposits located near major centers of industry and population have been depleted and mines are increasingly concentrated in more remote regions. Transport costs are a major determinant of competitiveness, and reductions in shipping costs since the mid-twentieth century have internationalized the markets for many products, like coal and iron ore, that formerly served regional or local markets. The European Union, Japan, and the United States have become increasingly dependent on imports, either of mineral raw materials, or of semi-processed products, to supply their requirements. The fast developing countries of the Asian Pacific Rim are also heavily reliant on imports of minerals. Economic growth in the latter region, combined with rapidly rising demand from China, is putting renewed pressure on mineral supplies. China has by far the world’s largest minerals industry, accounting for about 12 percent of global minerals turnover, excluding coal, and nearly 18 percent, including coal. Many, but by no means all, of its mines are antiquated, undercapitalized, small-scale operations with poor environmental and health and safety records.


Most minerals and their first-stage products are traded internationally at prices determined in global markets. Shifts in exchange rates and domestic economic policies thus influence an individual mine’s ability to compete. The amount of usable product contained in ore, its ease of processing, and accessibility are the main endogenous determinants of competitiveness. Energy is a large element of costs, so that rising oil prices have an adverse impact. Economies of scale are important, and the typical scale of operations has risen considerably over the past fifteen years. Many small mines have closed down, and larger mines have expanded, so that the number of mining operations has contracted. Technical change and rising productivity have also driven down costs.


Labor costs are relatively unimportant in many mines, although U.S. companies are often burdened by large legacy costs. Organized mining accounts for much less than 1 percent of the world’s workforce—fewer than 15 million people, with a further 11.5 to 13 million people working in small-scale mines. According to the International Labor Office, the total number of people relying on mining, both large and small, for a living, taking dependents into account, is about 300 million, of which up to one-third depend on small-scale mining. The numbers have fallen markedly since the 1980s with the closure of many small mines and improving productivity, especially in China. There is a growing global shortage of skilled and professional labor, because of a rundown in mining education and a lack of new entrants.


LABOR CONDITIONS AND STATE OF THE INDUSTRY

Mines are only located where there are viable ore deposits, and these are often in physically remote areas, far from major population centers. The modern tendency is for workers to commute to mine sites for extended shift periods of up to a month, from well-established communities with good infrastructure and social amenities. Before the development of low-cost air travel such commuting was seldom possible and dedicated mining camps were often established to house the workers, not always with their families. Such communities were natural breeding grounds for the social ills of alcohol abuse and prostitution. They also insulated workers from outside influences and fostered their solidarity. That was enhanced by the arduous and dangerous nature of mining, particularly when underground. Even minor grievances, real or imagined, could be blown up out of proportion. The conditions were ideal for periodic labor unrest and trade union militancy. Moreover, miners in rural areas could live cheaply, especially in the summer months when there were alternative agricultural, hunting, or fishing opportunities. That remains true in some regions, such as parts of Canada.


In practice union membership and militancy have not been significantly greater in most of the mining industry than in other sectors of economic activity. According to the Bureau of Labor Statistics, in the United States, for example, the 8 percent of workers in the mining industry that belong to a union compare with 7.8 percent for the private sector as a whole, 13 percent in manufacturing, and 36.5 percent in government. When strikes did occur, however, they were often longer and more acrimonious than elsewhere. The cyclical nature of most mineral markets contributed in that regard, as it still does. Workers naturally seek to increase their earnings when markets are buoyant, as in 2005 and 2006, and are more prepared to strike than when markets are depressed. At such periods employers aim to reduce their labor costs. Today that will be achieved mainly through agreed redundancies. Historically, however, wages were cut, with or without prior consultation with employees. Some of the most bitter and most prolonged strikes resulted from such actions, for example in the U.S. and U.K. coal industries during the late 1920s and 1930s. In North America a tradition of labor contracts covering three- to five-year periods even today may prompt strikes at their renewal, in the copper and nickel industries for example. In neither sector has there been any to compare in recent years with those of the 1960s.

Odatda, sanoat va aholining asosiy markazlari yaqinida joylashgan konlari yaroqsiz qilingan va konlari tobora ko'proq chekka hududlarda jamlangan. Transport xarajatlari Raqobat asosiy mezondir, va o'rta-XX asrdan beri yuk zararlar tushirilishi, ko'mir va temir rudasini kabi, avval, mintaqaviy yoki mahalliy bozorlarga xizmat edi, ko'p mahsulotlar uchun bozorlarga xalqaro qilgan.

Osiyo Tinch okeani, deyarli rivojlanayotgan mamlakatlar minerallar importiga shuning og'ir ishongan bor. Xitoy tez ortib borayotgan talabni bilan birga oxirgi viloyatida iqtisodiy o'sish, mineral yetkazib yanada yaqqolroq bosim bo'ladi.

Bu, ayniqsa, qachon yer osti, qazib olish qiyin va xavfli tabiat tomonidan ishlab chiqildi. Hatto kichik shikoyat, real yoki tasavvurdagi, mutanosib chiqishi puflandi mumkinmi. sharoitlar davriy laboratoriya beqarorlik va kasaba uyushma ekstremizmning uchun ideal edi.

Bu Kanada qismlari sifatida ko'rib, ba'zi hududlarda, haqiqiy qoladi.




amaliyot uyushmasi a'zoligiga va ekstremizmning iqtisodiy faoliyatning boshqa sohalarida nisbatan kon sanoatining eng muhim darajada katta emas. Amerika Qo'shma Shtatlarida Mehnat statistikasi byurosining, ko'ra, masalan, tog'-kon sanoatida ishchilar 8 foiz, bir butun sifatida xususiy sektori uchun 7,8 foiz, ishlab chiqarish 13 foizga, va 36,5 foiz bilan solishtirish bir ittifoq tegishli edi hukumatidagi. tashlashlar kallangga Biroq, theywere o'ta uzoq va boshqa joylarda ko'proq jahldor. eng mineral bozorlar davriy tabiati u hali kabi, hisobga dass hissa qo'shgan. bozorlar, 2005 va 2006-yilda bo'lib, suzib yuruvchi va bozorlar tushkunlikka Qachon ortiq urishni ko'proq tayyor bo'lgach Ishchilar tabiiy Ularning daromad oshirish talab. ko'rib davrlarda ish beruvchilar, ularning mehnat xarajatlarini kamaytirish niyatidamiz.
