Mine (novel)

Mine is a novel written by American author Robert R. McCammon. It won the 1990 Bram Stoker Award for Best Novel.

Plot summary

The novel tells the story of Laura Clayborne, a successful journalist, the wife of a stockbroker and mother-to-be. With her life seemingly falling apart, Laura hopes that her newborn son, David, will make her life everything it ought to be.

Mary Terrell, aka Mary Terror, is a survivor of the radical 1960s and a once a member of the fanatical Storm Front Brigade. Mary lives in a hallucinatory world of memories, guns, and above all, murderous rage. After viewing an ad placed in a popular magazine, she becomes convinced that the former leader of the Brigade, Lord Jack, is commanding her to bring him the child she was carrying when her life was suddenly turned upside down.

Mary steals Laura's baby and the manhunt is on. With no help at all Laura sets out on a cross-country trip to reclaim that which is hers. But soon Laura realizes that in order to get back her son and her life she may have to become as savage as the woman she's hunting.

Mining

Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, reef or placer deposits which forms the mineralized package of economic interest to the miner.

Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.

Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed.

Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world's nations have passed regulations to decrease the impact. Worker safety has long been a concern as well, and modern practices have significantly improved safety in mines.

Naval mine

A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, an enemy vessel. Naval mines can be used offensively—to hamper enemy shipping movements or lock vessels into a harbour; or defensively—to protect friendly vessels and create "safe" zones.

Description

Mines can be laid in many ways: by purpose-built minelayers, refitted ships, submarines, or aircraft—and even by dropping them into a harbour by hand. They can be inexpensive: some variants can cost as little as US$1000, though more sophisticated mines can cost millions of dollars, be equipped with several kinds of sensors, and deliver a warhead by rocket or torpedo.

Their flexibility and cost-effectiveness make mines attractive to the less powerful belligerent in asymmetric warfare. The cost of producing and laying a mine is usually anywhere from 0.5% to 10% of the cost of removing it, and it can take up to 200 times as long to clear a minefield as to lay it. Parts of some World War II naval minefields still exist because they are too extensive and expensive to clear. It is possible for some of these 1940s-era mines to remain dangerous for many years to come.
