Quartz Ore Mining

Quartz mining is used to mine quartz and produce quartz sand and powder. Main usages of quartz are: in metallurgy industry, quartz is used to make acid firebrick—silica bricks and various metallic fluxes, which are the main raw materials to smelt iron and silicon steel; pure quartz can also be used to manufacture silica grass and refine crystal silicon--monocrystal line silicon, also to make sial and organic silicon. In industry of building materials, quartz is the major raw materials of plate grass and ware glass. In chemical industry, it is used to make various silicon compound, silicate, and padding of sulphuric acid. In addition, it is used to make millstone or oilstone for grind.

Quartz mining plant

Mining of quartz stone has a long history. High efficiency and high out-put are always the goals which miners make direct efforts to pursue. With explosive, low out-put will be got. However, adopting hydraulic rock-splitting machine, out-put will be largely improved. Static security work, featuring with fast speed and lower cost, is the ideal method.

Technology of exploit quartz stone by rock-splitting machine

Plants: One set of motor-driven (diesel) type rock-splitting machine, two blower guns, accessory appliance, shovel, crow bar, sledge, etc.

Drill hole: Dimension of hole is 42mm, depth is 55cm, and hole pitch is 50cm. several holes are drilled in one quartz.

Split: Insert splitting heads, which split meanwhile. Just in several seconds, lump quartz is split immediately. It is the highest out-put in history.

Removal: After splitting, clear up quartz.

Comparison of Benefits

Manual knock: it is hard to split rock through manual knock and cost lots of time, with large labour intensity.

Splitting rock by rock-splitting machine: hydraulic rock-splitting machine, assorted with wind gun, is adopted in mining of rock. It features with low cost, high working efficiency and good economic benefit. This machine, with short splitting time and high out-put, can keep quartz complete and its fine quality; comparing with manual knock, it has low mining cost, super high efficiency.

Safe production in quartz mining

Security of Ventilation System of Mine

In middle-lower part of working, main fan, which can works constantly, should be installed in mine with special maintenance and management. In order to prevent obstruction of airway caused by collapse, return airway should be repaired timely. Along the change of work area of digging, build assorted ventilation buildings in time. Air door is fixed when using, which can prevent air escape branch that can cause circulate of polluted wind.

Safety of Drainage System of Mine

According the climatic attributes of mine area, calculate catchment area of mine lot and maximum rainfall catchment in storm season. Set waterway above the footrill and mouth of air shaft, which can prevent rainfall from sudden flocking to well.

In order to make sure that water flows to sump smoothly, clean up periodically the sundries in waterway of haulage drift, remove stagnant water in time;

In order to ensure safe operation, strength daily management of pumping appliance and drainage system and prepare enough anti-flood equipment;

Strength observations and analysis on discharge of water in mine, and seriously make analytical record of operation of draining pump. If abnormal water burst happens, start flood-prevention emergency preplan immediately;

In process of digging, strictly comply with principle of “exploration first then digging, exploration of every doubt”. Obverse water burst carefully, preventing damage of workers caused by the sudden surge of fault water, fracture water, and cavern water.

Safety of Mine Ground Pressure of Mine

Fix the reasonable blasting parameter, control explosive charge in strict accordance with requirements of blasting design. Interval delay blasting is carried out to reduce vibration of blasting.

Fulltime stuff take charge of management of ground pressure, adopt advanced monitoring equipments, build up fixed observation point (net), master change of ore-rock at any time; once find omen of ground pressure activities of large area, stop production immediately and withdraw workers and plants.
