Kanowna Belle gold mine in Kalgoorlie. Figure 10 shows the stoping sequence for a mining block where the extraction sequence was based upon a primary stope extraction and filling with consolidated fill, before the secondary pillars were extracted. The numbers on the figure refer to the stope extraction sequence.
Primary and Secondary "159" (or "147") Stope Sequence. By still using the general triangular retreat shape of a pillarless sequence but instead using an arrangement of small lift primary and secondary stopes, a compromise can be made. This increases the productivity by making multiple primary stopes available for mining simultaneously.
Definition: A primary economic activity is a type of operation or industry that involves extracting or refining natural resources, such as mining, agriculture, forestry, and economic functions deliver the raw material for other industries, which further refine and develop these materials into products to sell to customers.
What are the sectors of the economy? Human activities which generate income are known as economic activities. Economic activities are broadly grouped into primary, secondary, tertiary activities. Higher services under tertiary activities are again classified into quaternary and quinary activities. Let us first understand the differences between the different sectors of the economy, so that it ...

Sep 13, 2018· Primary, secondary, and tertiary structure are three, structural arrangements of proteins. The basic unit of all of the structures is the amino acid sequence, which is the primary structure of protein. Secondary structure of protein is formed from its primary structure, which in turns form the tertiary structure.
The primary sector of the economy extracts or harvests products from the earth such as raw materials and basic foods. Activities associated with primary economic activity include agriculture (both subsistence and commercial), mining, forestry, grazing, hunting and gathering, fishing, and packaging and processing of raw materials are also considered to be part of this sector.

A separate secondary pump delivers variable flow to the secondary loop and twoway valves are applied to control flow through each zone. Pros/Cons: This simple design typically has a low first cost and good flexibility. It also decreases the complexity of the chiller or boiler staging and control by eliminating on/off valves and min/max flow requirements. However, efficiency is limited because ...
Each step represents the distance away from the natural environment; primary industries extract natural resources while secondary industries turn those resources into products. Examples of primary sectors of industry including agriculture, mining, oil exploration, forestry, farming, fishing and hunting.
Primary structure is sometimes mistakenly termed primary sequence, but there is no such term, as well as no parallel concept of secondary or tertiary sequence. By convention, the primary structure of a protein is reported starting from the amino terminal (N) to the carboxyl terminal (C), while the primary structure of DNA or RNA molecule is ...
