* MINING MACHINERY

PURPOSE

To provide detailed data on quantity and total value of shipments for mining machinery and mineral processing equipment. The United States Code, Title 13, authorizes this survey and provides for mandatory responses.

COVERAGE

All firms that manufacture underground mining machinery; mineral processing machinery and equipment; portable oil and gas and water drilling rigs; and related equipment (Census Product Classes 3531-P, 3535, and part of 3743). In 1993, the value of manufacturer shipments of selected types of mining machinery amounted to over $1.2 billion.

CONTENT

Data are collected on over 40 types of mining and processing equipment. Product data at the 7-digit SIC level include quantity and value of shipments.

FREQUENCY

Annually; reported data are for activities taking place during the previous calendar year. Data on mining machinery and equipment have been collected since 1961.

METHODS

A mail-out/mail-back survey of 164 known manufacturers. Firms are identified from the latest census of manufactures, the Standard Statistical Establishment List, and private sources. Firms are contacted using form MA35F. Data may be revised if firms later provide corrected data. Annual figures are compared with data collected from the annual survey of manufactures to reconcile any differences between the two series.

* Terms

Mining machinery.Heavy machinery and equipment used by the mining industry in the exploration and devel- opment of solid mineral properties.Mining is used here in the broad sense to include the extraction of solid minerals occurring naturally such as coal and ores.The term min- ing also includes quarrying,milling (crushing,screening, washing,flotation,etc.),and other preparations customar- ily done at the mine site or as a part of mining activity.

Portable drilling rigs for use in oil and gas fields or for drilling water wells are also included for the purpose of this survey.

Auger drills.Machines that use continuous flight auger bits for removing cuttings.

Bucket drills.Machines that rotate a bucket and remove cuttings by lifting the bucket to be dumped.

Cable tools.Machines using percussion-type tools and those that clean the hole using tubular-type bailing tools.

Portable drilling rigs.Drills mounted on a carrier and used on the surface (above ground).

Pull-back capacity.Lifting capacity of drawworks or hoisting capacity of taphead.

Pull-down capacity.Capacity to apply bit pressure. Reverse circulation.Machines using a rotary drilling process where the drill cuttings and fluid return to the sur- face inside the drill stem (large diameter holes,18 or larger).

Rotary drills.Machines using rotary drill pipe,continu- ous fluid,and a mud pump,air compressor,or combina- tion to clear the hole of filling.

Screens,vibrating.Machines used for dry or wet screen- ing applications such as sizing,washing,and dewatering of ores,coal,sand,and gravel.

Unit.Complete rig,including carrier.
