explain in detail how the fire is controlled in caol mines

Answer:
Injection of inert gases and foams. Injecting inert gases is normal method to prevent and control coal seam fire because inert gases can be obtained easily and cheaply. However, in many cases, inert gases cannot be kept around the fire area for a long time.

Answer: Static means lacking in movement, action, or change, especially in an undesirable or uninteresting way.
In physics it means concerned with bodies at rest or forces in equilibrium.
Explanation:
1.In some programming languages such as C (and its close descendants like C++, Objective-C, and Java), static is a reserved word controlling both lifetime (as a static variable) and visibility (depending on linkage). The effect of the keyword varies depending on the details of the specific programming language.
2.Common C/C++ behavior
In C and C++, the effect of the static keyword in C depends on where the declaration occurs.
static may act as a storage class (not to be confused with classes in object-oriented programming), as can extern, auto and register (which are also reserved words). Every variable and function has one of these storage classes; if a declaration does not specify the storage class, a context-dependent default is used:
extern for all top-level declarations in a source file,
auto for variables declared in function bodies.
