Apparatus of mine hoist communication and signaling of АСШП type

Apparatus of mine hoist communication and signaling of АСШП type is designed to coordinate the operating staff actions during lowering and lifting operations in the mine shafts.
The apparatus can be used for operative (or reserve) signaling according to the existing regulations. The apparatus is designed to operate in coal mines including those hazardous of gas (methane) and/or coal dust.
The equipment can be used in cold, temperate and tropical climate. In the 2012 apparatus of АСШП type was declared the winner of the All-Ukrainian competition «100 best goods of Ukraine» regional stage, nomination «industrial purpose goods».
Designer and Manufacturer: PJSC“DEG”

FUNCTIONS

The apparatus of АСШП type support the following:

  • Setting the hoisting plant operation modes from the signaling panel;
  • Setting the cage address, i.e. level, which the cage is addressed to and which is granted the right of running signals injection;
  • Operating modes and working levels signaling;
  • Running signals injection by means of buttons as well as signals “Stop” and “Breakdown”, additional signals injection using the buttons marked “People”, “Drilling and Blasting Operations”, “Patient”;
  • Direct injection of the «Stop» signal to the engine room from any signalingl panel;
  • Injection of the «Ready» signal from assistants signaling panels to signaling panel of the corresponding banksman or lander;
  • On the single-ending skip hoisting installations injection of the «Start» signal from the skip loading/unloading areas; while on multilevel hoisting installations signaling should be allowed from the working level;
  • Injection of the «Breakdown» signal from the banksman, landers and their assistants signaling panels with a direct transmission to the driver signaling panel and indication of the signal on all the signaling panels;
  • Giving the operating mode signals, level numbers and «Breakdown» signal (in the «dry contact» form) to be used in the hoisting installation control and protection circuits;
  • Duplication of the running signals and “Stop” signal presentation on the driver signaling panel;
  • Signaling of mine hoist machinery and equipment position (or state): mine shaft doors; landing chairs (rests, end-hinged rails), filling of the hopper feeder, filling of the receiving hopper, swinging gate, invalid lifting of the balancing rope loop, unplugging of the brake cables;
  • Signaling circuits operating check;
  • Control and display of communications between the apparatus components on the driver signaling panel;
  • Apparatus connectivity with mine process control system, as well as the ap-paratus components diagnostic data transfer to the mine technical support service or manufacturer;
  • Staff two-side loudspeaking communication.

IDENTIFICATION CODE STRUCTURE

АСШП – apparatus of mine hoist communication and signaling of АСШП type:

  • X – hoisting installation type: «К» — cage, «С» — skip;
  • ХХ – number of serviced levels;
  • У – climatic version according to ГОСТ 15150-69;
  • 5 – location category according to ГОСТ 15150-69.
ADVANTAGES OF USING

Apparatus of mine hoist signaling used on the vast majority of existing mines in CIS is based on the principle of multiple direct connections between staff (banksman, landers, their assistants and hoist driver) panels and ladder logic. This approach does not meet modern requirements for ergonomics and reliability of the apparatus of АСШП type and makes it not possible to implement a number of necessary and useful functions.
The apparatus of АСШП type is manufactured using modern electronic components and taking into account modern safety and ergonomics requirements.

The main advantages of АСШП apparatus are:

  1. The АСШП apparatus design is based on the principle of remote systems using fieldbus (RS485 interface). This makes it possible to extend the range of features and functions significantly, as well as to increase apparatus reliability over the existing equipment used in mining conditions;
  2. Apparatus design modularity. Through the implementation of this technical solution makes it possible to simplify the process of maintenance and repair, as well as to increase reliability significantly;
  3. The use of high-speed programmable controller (PLC) makes it possible to expand the number of realizable functions significantly, as well as to realize the record of events and mine hoist operators
    commands.
  4. PLC performance capabilities allow operatively change the system algorithm for the pur-pose of a various additional functions implementation and a flexible adjustment to meet the specific operating
    conditions;
  5. Explosion protection type of the shaft signal system staff control and display panels is «intrinsically safe electrical circuit». This makes it possible to improve the ergonomics of equipment significantly,
    to use modern control and display devices, as well as to carry out maintenance and repair without powering down the entire system.
OPERATION CONDITIONS

Ambient temperature:

  • for the components located in the machine room, from + 1 to 40° C;
  • for the components located on the zero level, from — 20 to + 35° C;
  • for the components located on the 1…X level landings, from — 5 to + 35° C;
  • relative humidity is up to (98 ± 2) % at the temperature of (25 ± 2)° C;

Rated values of the external ambient factors correspond to mechanical category M1 according to IEC 721-3-3-87.

OPERATIONAL LOCATIONS

In 2010, the first piece of АСШП apparatus was delivered to the mine «Krasnolimanskaya» (Ukraine), where it is successfully operated up to date.
Besides this, the АСШП apparatus is mass-used at such coal mining enterprises as: PJSC «Krasnodonugol» (Ukraine), DTEK Dobropolyeugol LLC (Ukraine), etc.
Also АСШП apparatus is successfully operated abroad (Georgia).

MANUFACTURER WARRANTY

Warranty operation life is 12 months from the date of commissioning.
Warranty operation life of the installations exported is not more than 18 months from the date of the state border crossing.
